Rolex GMT-Master II „Zombie” 126713GRNR Jubilee, Oystersteel and 18-karat yellow gold

The Rolex GMT-Master II „Zombie” with reference 126713GRNR is a modern luxury travel watch combining Oystersteel with 18-karat yellow gold in the distinctive Yellow Rolesor configuration. The model features a black dial, a two-tone grey-black ceramic Cerachrom bezel insert, an additional 24-hour hand in yellow gold, and a five-piece link Jubilee bracelet.

Reference 126713GRNR was presented by Rolex in 2023. It was one of two models on which the new grey-black Cerachrom insert debuted for the GMT-Master II collection. The other was the all-18-karat yellow gold reference 126718GRNR. Rolex highlighted the contrast between the shine of yellow gold and the dark, subdued color scheme of the grey and black ceramic.

The term „Zombie” is not an official name given to the watch by Rolex. It is a nickname that circulates within the collector community and the professional watch market. You may also encounter the term „Bumblebee” in listings, and occasionally other nicknames referring to the grey-black bezel and yellow gold. However, there is no officially approved name for this variant by Rolex beyond GMT-Master II 126713GRNR.

The correct full identification of the watch is:

Rolex Oyster Perpetual GMT-Master II 126713GRNR „Zombie”, Yellow Rolesor, black dial, grey-black Cerachrom bezel, Jubilee bracelet.

Yes. Rolex uses scratch-resistant sapphire crystal.

What is the water resistance?

100 meters, i.e., 330 feet.

Can you swim in the Rolex GMT Zombie?

The technical specification of 100 meters allows normal contact with water while maintaining the watch's seal. For a used exemplar before swimming, it is worth performing a water resistance test.

Does it have a Triplock crown?

Yes. The crown is screw-down and uses the triple waterproofing system Triplock.

Can the crown be operated underwater?

Do not unscrew or operate the crown underwater.

What bracelet does the Rolex Zombie have?

Reference 126713GRNR is equipped with a five-piece link Jubilee bracelet.

Is this the original Jubilee configuration?

Yes. Jubilee is the factory bracelet for this variant.

How many elements does a single row of Jubilee have?

The characteristic Jubilee construction consists of five elements across the width of the bracelet.

When was the Jubilee bracelet created?

Rolex created Jubilee specifically for the launch of the Oyster Perpetual Datejust in 1945.

Is Jubilee more comfortable than Oyster?

Comfort is a matter of individual preference, but the five-piece construction of Jubilee is very flexible and conforms well to the shape of the wrist. Rolex itself describes it as fluid and comfortable.

Are the center elements of Jubilee gold?

In the classic Yellow Rolesor configuration, the center elements of the bracelet are made of yellow gold, and the outer ones of Oystersteel. This is a characteristic Rolex Rolesor architecture.

What clasp does the Rolex Zombie have?

The bracelet is equipped with an Oysterlock folding safety clasp.

Does it have Easylink?

Yes. Easylink allows quick extension of the bracelet length by approx. 5 mm.

Does it have Glidelock?

Does Easylink require tools?

No. Its main advantage is the ability to quickly increase the bracelet circumference without a visit to a watchmaker.

Does the Rolex Zombie glow in the dark?

Yes. The hands and indices use the Chromalight system with long-lasting blue luminescence.

Is the 126713GRNR a men's watch?

Rolex does not need to be classified solely by gender. The case is 40 mm, so the model can be worn by anyone who likes its size and style.

Is the Rolex Zombie suitable for daily wear?

Yes. The steel case construction, Cerachrom, sapphire crystal, automatic movement, and water resistance to 100 meters make it a practical daily watch. However, gold elements require more caution than steel.

Will the gold elements scratch?

Yes. 18-karat gold is more susceptible to micro-scratches and dents than Oystersteel.

Where do scratches appear fastest?

The most visible are usually on the polished center links of the bracelet, the clasp, the crown, and other surfaces of yellow gold.

Can the Jubilee stretch?

Intensive, long-term use of any mechanical bracelet can lead to the formation of larger clearances between its elements. Regular cleaning reduces the effect of dirt particles that accelerate wear.

Can the gold elements be polished?

Yes, but polishing should be done professionally and sparingly. Too intensive processing can change the edges and factory geometry of the elements.

Does the Rolex Zombie go with a suit?

Yes. Jubilee and yellow gold give it a more elegant character than many other professional GMT-Master II models. The black dial and dark bezel balance the gold, allowing the watch to blend well with navy, black, grey, white, brown, or beige.

Does the Rolex Zombie go with everyday styling?

Yes. It can be combined with a shirt, blazer, polo, T-shirt, knitwear, and smart casual style.

Is it more elegant than the Batman or Batgirl?

This is a matter of style, but the use of 18-karat yellow gold and Jubilee makes the 126713GRNR have a more jewelry-like character than the steel 126710BLNR.

Is it more discreet than the Root Beer?

The 126713GRNR uses yellow gold, which is very visible, but the grey-black bezel is more neutral in color than the brown-black CHNR bezel. The final perception therefore depends on lighting and styling.

How does the Zombie differ from the full-gold 126718GRNR?

The 126713GRNR uses Yellow Rolesor, i.e., Oystersteel and yellow gold. The 126718GRNR is made entirely of 18-karat yellow gold. Both references were presented in 2023 with the new grey-black Cerachrom insert.

How does 126713GRNR differ from the steel 126710GRNR?

The 126713GRNR is steel-gold and was presented in 2023. The 126710GRNR made of Oystersteel appeared in 2024 and can be found on Oyster or Jubilee. The steel model also uses green accents on the dial and GMT hand.

Is the Rolex Zombie limited?

There is no official information that the 126713GRNR is a numbered limited edition.

Is the Rolex Zombie still in production?

Yes. As of August 7, 2026, reference 126713GRNR is in the current Rolex catalog.

How much does a Rolex GMT-Master II 126713GRNR cost at Rolex?

On the official Spanish Rolex website, the price of reference 126713GRNR was 20,000 euros on August 7, 2026. The catalog price may be updated by the manufacturer.

Does the market price have to match the catalog price?

No. The price on the professional independent market depends on current availability, demand, year of manufacture, card date, condition, completeness, exchange rates, and place of sale.

Can you buy a Rolex Zombie without a waiting list?

Yes. On the professional independent market, you can find specific exemplars available without waiting for an allocation in an official boutique.

Is the Rolex Zombie a good travel watch?

Yes. The GMT-Master was created in the context of international travel, and the independent regulation of local time is one of the most practical complications for people who regularly change time zones.

Does the GMT-Master II show Greenwich Mean Time?

The name GMT comes from Greenwich Mean Time. However, the user can set the 24-hour hand to any chosen reference zone. It does not have to be the current time in Greenwich.

Is the Rolex Zombie a collector's watch?

It may be attractive to collectors due to the launch of the grey-black Cerachrom insert in 2023, the Yellow Rolesor configuration, Jubilee, and distinct aesthetics. However, this does not mean a guarantee of value increase.

Is the Rolex Zombie an investment?

One should not present the watch as a sure investment. Prices can both rise and fall.

What affects the value of a specific exemplar?

Condition, year of manufacture, completeness, card, remaining manufacturer warranty period, bracelet condition, service history, lack of non-original modifications, case geometry, and current demand are significant.

Is Full Set important?

Yes, especially for some collectors and for later resale.

What does Full Set mean?

It most often means a watch along with the original box, warranty card, documentation, card case, tags, and other elements specific to the given year. The exact content should be confirmed each time.

Do Box & Papers guarantee authenticity?

No. The box and documents can be forged or come from another exemplar. Authenticity should be assessed based on the entire watch.

Can you buy a 126713GRNR without a card?

Yes, but the lack of a card can affect the value, collector appeal, and later resale.

How to check the authenticity of the Rolex Zombie?

Professional inspection should include the case, reference, serial number, dial, hands, date window, Cyclops, Cerachrom bezel, Jubilee bracelet, clasp, caliber 3285 mechanism, documents, and the compatibility of all elements with the specific configuration.

Is the serial number enough to check authenticity?

No. The number alone is not sufficient proof.

Do you need to check the mechanism?

In the case of comprehensive authentication, checking the mechanism can be a very important stage.

Can modern replicas of the 126713GRNR look similar?

Yes. Therefore, self-assessment of photos or numbers should not replace professional watch inspection.

Is it worth buying an unworn watch?

For some collectors, preserving factory geometry is very important. An unworn watch with normal signs of use may be more attractive than an intensively polished exemplar.

Is a watch after professional service worse?

No. A correctly performed and documented service can be an advantage.

Can M&M GOLD import a Rolex Zombie 126713GRNR?

Yes. M&M GOLD can search for a specific reference and exemplar compliant with the client's requirements.

Can a specific year of the watch be determined?

Yes.

Can you order only an unworn 126713GRNR?

Yes, depending on current availability.

Can you require Full Set?

Yes.

Can you require an unworn exemplar?

Yes. The case condition can be indicated as a sourcing condition.

Can you determine the Rolex card date?

How long does sourcing take at M&M GOLD?

Standardly, the sourcing process closes on average within 7 to 14 working days.

Is a deposit required for sourcing?

For individual sourcing, full prepayment is required, not a partial deposit.

Is the watch checked before release?

Yes. The inspection covers reference compatibility, condition, mechanism, completeness, and other elements important for the specific exemplar.

Does the watch have an M&M GOLD warranty?

Imported watches have a minimum one-year warranty on the mechanism in accordance with M&M GOLD sourcing conditions.

History of the Rolex GMT-Master and GMT-Master II

The history of the GMT-Master begins in 1955, during the rapid development of intercontinental aviation. Travel between continents was becoming faster, and pilots and passengers began to regularly cross many time zones during a single flight.

Rolex created the GMT-Master as a watch allowing simultaneous control of time in two different zones. The model was adopted by, among others, the crews of Pan American World Airways, better known as Pan Am, and became one of the most recognizable watches associated with civil aviation.

The abbreviation GMT comes from Greenwich Mean Time, the historical time standard associated with the prime meridian in Greenwich, London. Indicating the second zone in the watch is realized by an additional hand completing one rotation in 24 hours and a bezel with a 24-hour scale.

In 1982, Rolex presented the GMT-Master II. The new construction allowed independent regulation of the local hour hand. This seemingly minor change was a very important functional feature. A traveler arriving in a new zone could change the local time without stopping the watch and without disturbing the reference time indicated by the 24-hour hand.

Over time, the GMT-Master II became one of the most recognizable Rolex Professional collections. More combinations of materials and colors emerged, and the two-tone bezel became the visual hallmark of this family.

History of GMT-Master II ceramic bezels

The modern history of the GMT-Master II is strongly linked to the development of Cerachrom technology.

Rolex introduced increasingly advanced two-tone ceramic inserts. In 2013, a blue-black one-piece Cerachrom was presented, in 2014 a red-blue version, in 2018 a brown-black one, in 2022 a green-black one, and in 2023 the grey-black GRNR combination.

In 2024, the grey-black combination was extended to steel versions 126710GRNR. This shows that the variant presented a year earlier in gold and Yellow Rolesor became the basis for the next part of the modern GMT-Master II range.

Launch of the Rolex GMT-Master II 126713GRNR in 2023

The year 2023 is key to the history of the „Zombie”.

Rolex presented two GMT-Master II models with a completely new Cerachrom color combination: Yellow Rolesor 126713GRNR and full-gold 126718GRNR.

The manufacturer described the combination of shiny yellow gold with dark, subdued shades of the bezel as a reference to the rhythm of day and night. The black dial and 24-hour indication elements further strengthened the contrast.

The 126713GRNR version is particularly characteristic because it combines the professional construction of the GMT-Master II with Jubilee and Yellow Rolesor. Thanks to this, the watch is simultaneously sporty, travel-oriented, and significantly more jewelry-like than the steel variants of the collection.

Yellow Rolesor in the Rolex GMT-Master II

Rolex has used the name Rolesor since 1933, although combinations of gold and steel appeared in the brand's watches even earlier.

The idea is simple: combine the resistance and technical character of steel with the prestige and warm color of gold.

In the typical Yellow Rolesor configuration, the bezel, crown, and center links of the bracelet are made of yellow gold, while the middle part of the case and the outer links of the bracelet are made of Oystersteel.

In the 126713GRNR, the contrast is particularly readable thanks to Jubilee. The narrow, polished center elements of the bracelet create a gold line running through its entire length, while the steel outer elements visually balance the whole.

Thanks to this, the watch does not have the heavy visual character of the full-gold 126718GRNR, but is more luxurious than the steel 126710GRNR.

Black dial of the Rolex 126713GRNR

The dial is black and was designed to maintain the high legibility typical of professional Rolex watches.

The indices have simple geometric forms, using circles, rectangles, and the characteristic triangle at 12 o'clock. The wide hour and minute hands are easy to recognize, and the separate 24-hour hand allows for quick distinction between local time and reference time.

At 3 o'clock, there is a date window covered by a Cyclops lens.

The black of the dial also performs an important stylistic function. It connects with the black half of the Cerachrom and balances the warm glow of yellow gold.

Grey-black Cerachrom bezel

The most characteristic element of the „Zombie” is its grey-black bezel.

The two-tone Cerachrom insert is made of high-technology ceramic. It is resistant to corrosion and exceptionally resistant to typical scratches. The color of the ceramic was developed to maintain stability despite the action of ultraviolet radiation.

The grey half is significantly more neutral than the red of the „Pepsi”, the blue of the „Batman”, or the brown of the „Root Beer”.

As a result, the 126713GRNR has a distinct contrast between materials, but the bezel itself is relatively subdued.

In bright light, the grey can be very pronounced. In weaker lighting, its tone optically approaches black, allowing the bezel to look almost monochromatic.

Bidirectional 24-hour bezel

The bezel can rotate in both directions.

Its primary function is to work with the 24-hour hand. In the standard position, the hand shows the reference time.

If the user rotates the bezel by the appropriate number of hours, they can use the same hand to observe time in the next zone.

The GMT-Master II can therefore be used to control even three time zones, despite having only one additional GMT hand.

GMT hand

The 24-hour hand is finished with a characteristic triangular arrowhead.

In contrast to the regular hour hand, it completes one full rotation per day, not two.

If it is, for example, at numeral 18 on the bezel, the reference time is approximately 18:00, regardless of what time the main hands show locally.

The solution also allows easy recognition of whether it is day or night in the second zone.

How does the independent hour hand work?

This is one of the most important technical functions of the GMT-Master II.

Upon arrival in a new time zone, the user does not need to reset the entire watch.

The local hour hand can be moved in jumps of full hours forward or backward. The minute, second, and 24-hour hands remain set relative to the reference time.

This allows changing the local time without losing the precise setting of the watch.

Date window and Cyclops lens

The Rolex 126713GRNR has a date window at 3 o'clock.

Above the date is the Cyclops lens, one of the most characteristic design elements of modern Rolexes.

When buying a used exemplar, check the correct alignment of the date in the window, the operation of the date change, the condition of the crystal, and the lens.

In the GMT-Master II, the date is functionally connected with the local hour indication, allowing correct day change when crossing midnight during travel.

Rolex caliber 3285 mechanism

The heart of the 126713GRNR is the automatic caliber 3285 produced by Rolex.

The mechanism ensures central indication of hours, minutes, and seconds, 24-hour indication, independent fast regulation of the local hour hand, instantaneous date change, and a stop-seconds function allowing precise time setting.

The caliber uses automatic, bidirectional winding via the Perpetual rotor.

Rolex declares approximately 70 hours of power reserve.

Chronergy escapement

Caliber 3285 uses the Chronergy escapement developed by Rolex.

The construction was optimized for energy efficiency and reliability. In combination with the barrel architecture, it allows the mechanism to achieve approximately 70 hours of power reserve.

In practice, this is also significant during daily use. The watch does not need to be reset every time after a short break in wearing.

Parachrom spring

The oscillator uses the blue Parachrom hairspring.

Rolex uses a paramagnetic material whose properties help limit the influence of magnetic fields on the operation of the mechanism.

This is significant in the modern environment, where the watch may be near smartphones, computers, speakers, magnetic closures, or other devices generating magnetic fields.

Paraflex shock absorbers

Caliber 3285 has high-efficiency Paraflex shock absorbers.

Their purpose is to increase the resistance of the delicate oscillator to shocks.

This does not mean, however, that the watch should be worn during all activities. For weight training, contact sports, golf with very intensive use, or work with tools generating strong impacts, it is safer to remove the watch.

Power reserve of approx. 70 hours

Approximately 70 hours of power reserve means practically three days of operation after a full wind.

The actual value in a used exemplar may depend on the condition of the mechanism and service history.

A significantly shortened power reserve can be one of the signals indicating the need for diagnostics.

Precision -2/+2 seconds per day

Rolex declares for the 126713GRNR an accuracy of -2/+2 seconds per day after casing.

The parameter refers to the factory standard.

In a used watch, accuracy depends on the condition of the mechanism, regulation, service history, intensity of use, magnetization, and other factors.

Superlative Chronometer

The 126713GRNR is certified as a Superlative Chronometer.

The Rolex designation includes control of the complete watch, after placing the mechanism in the case.

The standard includes, among others, rigorous requirements for accuracy, automatic winding, power reserve, and water resistance.

Oyster case 40 mm

The case has a diameter of 40 mm and a classic Oyster architecture.

Rolex uses a monobloc middle case, a screw-down case back, and a screw-down crown.

The 40 mm size allows the watch to maintain a sporty presence without causing the impression typical of much larger modern 43 or 45 mm watches.

Triplock crown

The screw-down crown uses the Triplock system with three sealing zones.

The solution co-creates the water resistance to 100 meters declared by Rolex.

After each time adjustment, the crown should be properly screwed down.

Water resistance 100 meters

Rolex declares water resistance to 100 meters.

However, this parameter should not be unconditionally applied to every multi-year used exemplar.

Gaskets are elements subject to aging. If the watch's history is unknown or the case has been opened, it is worth performing a professional water resistance test before contact with water.

Sapphire crystal

The 126713GRNR has scratch-resistant sapphire crystal.

Sapphire has very high hardness, making its surface significantly more resistant to daily micro-scratches than older mineral or hesalite crystals.

A strong impact can still lead to chipping or cracking.

Chromalight

The wide hands and characteristic hour indices are covered with Chromalight luminescent material.

The system emits long-lasting blue light, facilitating time reading in the dark.

Legibility is one of the important elements of the construction of professional Rolex watches.

Jubilee bracelet

Jubilee is one of the elements giving the 126713GRNR its special character.

The bracelet was originally created in 1945 for the Datejust. It consists of five elements across the width, making it optically and mechanically more flexible than the classic three-link Oyster.

In the Yellow Rolesor configuration, Jubilee creates the effect of a characteristic golden axis running through the center of the bracelet, surrounded by steel elements.

The result is significantly more elegant than in typically sporty bracelets.

Jubilee vs. Oyster

For the GMT-Master II, the choice between Jubilee and Oyster can completely change the perception of the watch.

Oyster is visually simpler, more robust, and more tool-like. Jubilee, due to the greater number of elements, reflects light in a more complex way and has a more elegant character.

In the case of the 126713GRNR, Rolex offers the factory Jubilee configuration, which pairs well with the use of Yellow Rolesor.

Oysterlock clasp

The bracelet has an Oysterlock folding clasp.

The additional safety feature aims to reduce the risk of accidental opening.

When buying a used exemplar, check the operation of the entire mechanism, the level of play on the hinges, and signs of strong impacts.

Easylink system

Easylink allows quick extension of the bracelet length by approx. 5 mm.

It is particularly useful in summer, during flights, and during long-term wear, when the wrist circumference may increase slightly.

It does not replace proper adjustment of the number of links, but significantly increases comfort in daily use.

Is the Rolex Zombie suitable for everyday wear?

Yes.

The 126713GRNR is a very interesting compromise between luxury and functionality.

Steel elements reduce the susceptibility of the whole to damage compared to a watch made entirely of gold. At the same time, 18-karat yellow gold makes the watch present itself as significantly more luxurious than the fully steel variant.

Cerachrom, sapphire, water resistance to 100 meters, and caliber 3285 allow treating the GMT-Master II as a true daily watch.

How to care for Yellow Rolesor?

The greatest attention is required for polished gold elements.

The watch should be protected against impacts, contact with stone countertops, metal bracelets, diamond jewelry, and activities that may cause mechanical impacts.

The bracelet should be cleaned periodically, as dust, sand, and dirt particles accumulating between its elements can act abrasively.

Can you wear the Rolex Zombie with a diamond bracelet?

If we care about the condition of the watch, it is better not to wear a diamond bracelet directly next to the Rolex.

Diamond is significantly harder than 18-karat gold and steel and can cause visible scratches.

It is safer to wear jewelry on the other wrist.

How to evaluate a used Rolex 126713GRNR?

Professional evaluation should include case geometry, signs of polishing, condition of gold elements, condition of steel surfaces, ear edges, ceramic bezel insert, crystal and Cyclops, dial, hands, date window, operation of GMT function, operation of independent hour hand, mechanism accuracy, power reserve, crown, water resistance, Jubilee bracelet, level of play, Oysterlock clasp, Easylink, completeness of links, box, card, and service history.

In the steel-gold model, the condition of the polished elements of the bracelet made of 18-karat yellow gold is particularly important. Very deep scratches and dents may require intervention, which some collectors would prefer to avoid.

How to check the authenticity of the Rolex GMT-Master II 126713GRNR?

Authentication should concern the entire watch.

The appearance of the dial, serial number, or card is not enough.

Check the reference, case proportions, material, quality of polishing and brushing, Cerachrom bezel, fonts, dial, hands, Cyclops, date window, bracelet, clasp, markings, 3285 mechanism, and documentation compatibility.

Modern popular Rolex references are often copied, so professional inspection significantly reduces the risk of purchasing a non-original or incorrectly assembled exemplar.

New, unworn, or used Rolex Zombie?

The market offers new, unworn, used, serviced exemplars, and watches with varying remaining manufacturer warranty periods.

„Unworn” does not necessarily mean the current year or a card activated recently.

The physical condition of the watch and the date of its documentation should be evaluated separately.

What does Full Set mean?

Full Set most often means a watch along with the original box, warranty card, documentation, case, tags, and additional elements specific to the given period.

In the case of a used 126713GRNR, also ensure that the set contains all removed Jubilee links.

The lack of gold bracelet elements can generate noticeable costs for their later replenishment.

Rolex 126713GRNR vs. 126718GRNR

These are two models that presented the grey-black bezel in 2023.

The 126713GRNR uses Yellow Rolesor, i.e., a combination of Oystersteel and yellow gold. The 126718GRNR is made of 18-karat yellow gold.

The 126718GRNR is heavier, more jewelry-like, and has a significantly higher material value resulting from the amount of gold.

The 126713GRNR is more versatile for daily wear and visually lighter.

Rolex 126713GRNR vs. 126710GRNR

The steel 126710GRNR appeared in 2024, a year after the launch of the Yellow Rolesor version.

It has the same basic grey-black Cerachrom combination, but a completely different presence on the wrist.

The 126710GRNR is made of Oystersteel and has green accents. It is offered on Oyster or Jubilee. The 126713GRNR uses Yellow Rolesor and Jubilee.

For a person wanting the most discreet GRNR version, steel is the better choice.

For a person expecting a more distinct luxurious character, the Yellow Rolesor 126713GRNR is a natural step up.

Rolex Zombie vs. Root Beer

The Rolex „Root Beer” 126711CHNR uses Oystersteel and Everose gold with a brown-black bezel.

The 126713GRNR „Zombie” uses Oystersteel and yellow gold with a grey-black bezel.

Root Beer is warmer in color, with a rose-copper shade of gold and brown ceramic.

The Zombie gives a stronger contrast between bright yellow gold and neutral shades of grey and black.

The choice is therefore more a matter of stylistic preference than functional, as both watches use the GMT-Master II construction and 3285 movement.

Rolex Zombie vs. Batman and Batgirl

The terms Batman and Batgirl are used for the blue-black variants of the GMT-Master II BLNR, with „Batgirl” customarily associated with the Jubilee configuration.

The 126713GRNR differs from the BLNR primarily by the grey-black bezel and the presence of yellow gold.

Batman and Batgirl are more sporty and cool in color. The Zombie is significantly more luxurious and jewelry-like.

Who is the Rolex GMT-Master II Zombie for?

The 126713GRNR is particularly suitable for a person who wants a functional travel watch but does not want to choose either a completely steel model or a heavy full-gold GMT.

Yellow Rolesor gives a distinct luxury effect, Jubilee increases elegance, and the grey-black bezel remains neutral and easy to combine with a wardrobe.

This is a very interesting configuration for a person building a Rolex collection, which already includes classic steel models and needs a watch with a more distinct presence.

How to wear the Rolex Zombie?

The grey and black of the bezel make the watch surprisingly versatile.

It pairs very well with black, navy, grey, white, beige, brown, olive green, and denim blue.

Yellow gold can be used as a single luxurious accent without the need to add another piece of gold jewelry.

Jubilee allows wearing the model with both a T-shirt and polo, as well as with a shirt, blazer, or modern suit.

Rolex GMT-Master II „Zombie” as a collector's watch

The 126713GRNR has several features that may make it interesting for collectors.

It belongs to the first two references that received the grey-black Cerachrom insert in 2023. It is a Yellow Rolesor configuration, has Jubilee, and retains the characteristic GMT function.

In 2024, Rolex applied GRNR to steel models as well, which further solidified this color scheme as part of the modern GMT-Master II family.

This does not mean, however, that the watch is a sure investment.

Future value will depend on supply, demand, Rolex's product strategy, the luxury goods market state, and the quality of the specific exemplar.

Rolex Zombie without a waiting list

The Rolex GMT-Master II 126713GRNR can be bought on the professional independent market without waiting for an allocation of a specific exemplar in an official boutique.

The price may be lower, similar, or higher than the catalog price depending on the market situation.

Value is influenced by year of manufacture, condition, completeness, card activation date, remaining warranty period, availability, and demand.

Rolex GMT-Master II „Zombie” 126713GRNR from M&M GOLD experts

The Rolex GMT-Master II 126713GRNR „Zombie” is one of the most characteristic modern travel models from Rolex, combining Oystersteel, 18-karat yellow gold, a black dial, a grey-black Cerachrom insert, and a five-piece link Jubilee bracelet.

The reference was presented in 2023 and, along with the full-gold 126718GRNR, was the first to introduce the grey-black combination of the ceramic bezel insert to the GMT-Master II collection.

Beneath the sporty-luxurious construction lies the Rolex caliber 3285 movement. The automatic mechanism ensures the second time zone function, independent regulation of the local hour hand, a date window, approximately 70 hours of power reserve, and declared precision of -2/+2 seconds per day after casing.

Jubilee gives the model a more elegant character than a typical sporty bracelet. The use of Yellow Rolesor, on the other hand, causes the 126713GRNR to occupy an interesting place between the steel 126710GRNR and the all-gold 126718GRNR.

This is a watch for a person who expects a practical GMT function and a professional Rolex construction, but at the same time wants a distinct presence of 18-karat yellow gold.

Through M&M GOLD, you can order a specifically selected 126713GRNR exemplar, specifying the preferred year, condition.
