Rolex GMT-Master vs GMT-Master II: Differences, References and Which to Buy

The difference between the Rolex GMT-Master and GMT-Master II is the hour hand. On the GMT-Master, launched in 1955, the 12-hour and 24-hour hands are linked. The GMT-Master II, introduced in 1982, lets you jump the local hour hand on its own, so you can change time zones without stopping the watch or losing home time.

Key takeaways

• The original Rolex GMT-Master (1955 to 1999) shows two time zones. Its 24-hour hand is geared to the hour hand and cannot be set separately.

• The GMT-Master II (1982 to today) has an independently adjustable hour hand that jumps in one-hour steps, and it can show three time zones with the rotating bezel.

• Vintage GMT-Master references (6542, 1675, 16750, 16700) are bought for history, aluminum or Bakelite bezels, and aged lume. Modern GMT-Master II references use Cerachrom ceramic bezels and Caliber 3285, with about 70 hours of power reserve.

• Rolex removed the red-and-blue "Pepsi" GMT-Master II from its catalog at Watches and Wonders 2026, which makes pre-owned examples the only route to one.

• Reference number, originality, and service history affect a pre-owned Rolex GMT's value more than the model name does.

GMT-Master vs GMT-Master II: side-by-side comparison

The GMT-Master is a two-time-zone watch with linked hands, built from 1955 until 1999. The GMT-Master II is a three-time-zone travel watch with an independent hour hand, in production since 1982. The table below compares the two models on the points buyers ask about most.

Why did Rolex create the GMT-Master?

Rolex created the GMT-Master in collaboration with Pan American World Airways so that pilots on long-haul routes could read two time zones at once. The first reference, the 6542, was developed in 1954 and launched in 1955, and Pan Am issued GMT-Masters to its flight crews.

The idea was simple. A fourth hand made one revolution every 24 hours and pointed to a rotating bezel marked from 1 to 24. Set to Greenwich Mean Time, that hand gave crews a reference time for navigation, while the ordinary hands showed local time. The two-color bezel separated day from night at a glance, which is why red and blue became the model's first colors.

The ref. 6542 had no crown guards and a 38mm case. Its early bezel inserts were Bakelite with radium-painted numerals; they cracked easily, so Rolex moved to aluminum. A surviving Bakelite example is now one of the most sought-after vintage Rolex GMT watches. 

In 1959, the ref. 1675 replaced it with a 40mm case and crown guards, and it stayed in production until about 1980. The 16750 followed in 1981 with Caliber 3075 and a quickset date. The last GMT-Master, ref. 16700, ran from 1988 to 1999 with Caliber 3175 and a sapphire crystal.

What changed when the GMT-Master II arrived in 1982?

Rolex introduced the GMT-Master II in 1982 with a movement that let the hour hand be set independently of the other hands. That single change meant a traveler could reset local time on arrival while the 24-hour hand kept showing home time.

The first GMT-Master II, ref. 16760, used Caliber 3085 and a thicker case, earning it the nicknames "Fat Lady" and "Sophia Loren." It also introduced the black-and-red "Coke" bezel and a sapphire crystal. 

The slimmer ref. 16710 replaced it in 1989 and was sold alongside the GMT-Master 16700 for a decade, which is why "GMT-Master 16700 vs GMT-Master II 16710" is still a common question. The two look almost identical. The 16710's Caliber 3185 (later 3186) has the independent hour hand; the 16700's Caliber 3175 does not.

Ceramic arrived in 2005 on the yellow gold ref. 116718LN, then in steel with the 116710LN in 2007. Since 2018, the current 1267xx references have used Caliber 3285, which Rolex describes in its official GMT-Master II release notes as an in-house movement with the patented Chronergy escapement and about 70 hours of power reserve.

What is a "flyer" GMT, and how is it different from a "caller" GMT?

A "flyer" or "true GMT" lets you jump the local hour hand independently, which suits people who change time zones in person. A "caller" or "office" GMT lets you set the 24-hour hand independently instead, which suits people who stay put and track another zone from home.

The Rolex GMT-Master II is a flyer GMT. The original GMT-Master is not: its 24-hour hand is permanently geared to the hour hand, so you read the second zone by turning the bezel rather than moving a hand. For frequent travelers, the flyer layout is the most convenient of the three because the date also follows the local hour hand forward or backward.

Rolex GMT-Master and GMT-Master II reference and caliber timeline

Each Rolex GMT reference has its own movement, bezel material, and production window, and those details decide both function and value. Use this timeline to place any watch you are considering.

Some sources date the first 16760 deliveries to 1983. Rolex itself gives 1982 as the year the GMT-Master II was unveiled.

How do you set and use a Rolex GMT-Master and GMT-Master II?

On a GMT-Master, you set local time and the 24-hour hand moves with it; you then rotate the bezel to read a second time zone. On a GMT-Master II, you set home time on the 24-hour hand first, then jump the hour hand to local time. Our beginner's guide to the GMT bezel covers the basics with diagrams.

Setting a GMT-Master (refs. 1675, 16750, 16700)

1. Unscrew the crown. On a 16750 or 16700, the first pulled position sets the date quickly. A 1675 has no quickset date.

2. Pull the crown to the time-setting position and set the local time. The 24-hour hand follows the hour hand.

3. Push the crown in and screw it down fully to restore water resistance.

4. To read a second zone, rotate the bezel by the time difference. If you are in Miami and want London, turn the bezel so the 24-hour hand reads five hours ahead.

Setting a GMT-Master II (refs. 16760 onward)

1. Unscrew the crown and pull it to the last position. The seconds hand stops.

2. Set the 24-hour hand to home time, using the bezel at its neutral position (triangle at 12). The minute hand and hour hand move with it.

3. Push the crown to the middle position. Turn it to jump the hour hand forward or backward in one-hour steps to local time. The minutes, seconds, and 24-hour hand stay put, and the date changes when the hour hand passes midnight.

4. Screw the crown down.

Reading a third time zone with the 24-hour bezel

1. Note the time difference between home time and the third zone.

2. Rotate the bidirectional bezel by that number of hours.

3. Read the third zone where the 24-hour hand points on the bezel. Return the bezel to neutral to read home time again.

How did bezels, lume and materials change from vintage to modern?

Vintage GMT-Masters used Bakelite and then anodized aluminum bezel inserts, which fade with sunlight and age. Modern GMT-Master II watches use Cerachrom, Rolex's ceramic, which resists scratches and does not fade. That shift explains much of the gap in character, and in price, between the two families.

A faded aluminum Pepsi insert can turn pale pink and light blue, and collectors pay for that kind of honest aging. Ceramic offered durability, but producing two colors in one ceramic insert proved hard. Rolex managed blue and black first on the 2013 "Batman" ref. 116710BLNR, then red and blue in white gold in 2014. Our article on watch bezel types and functions explains how the materials compare.

Luminous material followed a similar path. The earliest 6542 dials used radium. Tritium followed and lasted until the late 1990s, and dials from that era often carry "T Swiss T" or "Swiss T<25" at six o'clock. Luminova, then Super-LumiNova, replaced it, and current models use Rolex's blue-glowing Chromalight. Tritium dials develop a cream or brown tone that vintage buyers prize.

Modern buyers can also choose by metal. The GMT-Master II comes in Oystersteel, Rolesor (steel and gold, such as the 126711CHNR in Everose Rolesor), solid Everose gold (126715CHNR), yellow gold (126718GRNR) and white gold. Bracelet options are the sporty Oyster and the five-link Jubilee, which returned to the steel line in 2018. If a gold or two-tone watch appeals, read our GMT-Master II two-tone buyer's guide.

Under the dial, Caliber 3285 adds the Parachrom hairspring and Chronergy escapement. Every current Rolex carries Superlative Chronometer certification, which Rolex specifies as plus or minus two seconds per day after casing, backed by a five-year international guarantee from the original date of sale.

Rolex GMT nicknames: Pepsi, Coke, Batman and the rest

Most Rolex GMT nicknames describe the bezel colors, and each one points to specific references. Knowing the reference matters more than the nickname, because the same colors appear on watches decades apart.

As of the 2026 catalog, the steel GMT-Master II is offered with Batman, Bruce Wayne, and Sprite bezels. We cover Pepsi's exit in our Watches and Wonders 2026 breakdown, and if you are choosing between the two most famous colorways, read Rolex Coke vs Pepsi: which one should you buy?

How can you tell a GMT-Master from a GMT-Master II?

The fastest check is the dial: a GMT-Master II reads "GMT-MASTER II," while the original reads "GMT-MASTER." The reference number engraved between the lugs at 12 o'clock confirms it, and the crown test confirms the function.

• Dial text: Look under the Rolex crown logo for "GMT-MASTER" or "GMT-MASTER II."

• Reference number: Four-digit references (6542, 1675) and the five-digit 16750 and 16700 are GMT-Masters. 16760, 16710, and every six-digit reference are GMT-Master IIs.

• Crown test: In the middle crown position, a GMT-Master II's hour hand jumps on its own. On a GMT-Master, the hands only move together.

• Bezel and crystal: A ceramic bezel means a GMT-Master II. An acrylic crystal means a pre-1988 GMT-Master.

Serial numbers help date the case; our Rolex serial number guide shows how to read them.

What is a Rolex GMT worth, and which holds its value best?

A Rolex GMT's value depends on the reference, the bezel, the dial, and how original the watch is. Modern steel GMT-Master II references have held their value well in recent years, while vintage GMT-Master values swing widely with condition and dial variant. No model is a guaranteed investment.

Within the vintage range, the 16700 and 16750 are usually the most attainable GMT-Masters, and a gilt-dial 1675 or a Bakelite-bezel 6542 sits at the top. The price spread within one reference can be large. These factors move it most:

• Dial variant: Gilt dials, early "Long E" dials, and documented rarities command premiums.

• Lume: Original tritium with even aging is worth more than a later Luminova service dial.

• Bezel insert: An original, period-correct insert with natural fading adds value; a modern replacement subtracts it.

• Case condition: Sharp, unpolished lugs and chamfers matter to collectors.

• Box and papers: A full set with the original warranty card supports both price and resale.

• Market events: Reports after Watches and Wonders 2026 noted a jump in secondary prices for the Pepsi once Rolex dropped it from the catalog.

Which Rolex GMT should you buy?

Buy a GMT-Master II if you travel and want the most practical Rolex for changing time zones. Buy a vintage GMT-Master if you value period details, aged materials, and the Pan Am era more than convenience.

• Frequent flyer: a current 126710 with Caliber 3285. The Batman, Bruce Wayne, and Sprite bezels are ceramic and will not fade.

• Neo-vintage buyer: the GMT-Master II 16710. It pairs an aluminum bezel with the independent hour hand, and its inserts come in Pepsi, Coke, or black.

• Vintage collector: a 1675 or 16750, where originality and provenance drive the purchase.

• Left-handed wearer: the Sprite 126720VTNR, with its crown and date on the left side of the case.

What should you check before buying a pre-owned Rolex GMT?

Start with the reference number, then confirm the movement, dial, hands, bezel, and bracelet match that reference. A pre-owned Rolex GMT can look right and still be a mix of parts from different decades. Our step-by-step guide on how to buy a pre-owned Rolex covers the basics; these are the GMT-specific red flags.

• Movement mismatch: A 16710 should carry a Caliber 3185 or 3186, and a 16700 a Caliber 3175. Any other movement is a warning.

• Service replacement dials and hands: Rolex often replaced tritium dials during servicing. A Luminova dial in a 1970s case is correct as a service part but worth less to collectors.

• Aftermarket bezel inserts: Reproduction aluminum inserts, sometimes artificially faded, are common on vintage GMTs. Check the font and the shape of the triangle at 24.

• "Frankenwatches": Watches assembled from a genuine case with non-matching dial, movement, or bracelet parts.

• Over-polished lugs: Rounded lug edges and a thinned case profile reduce value and cannot be fully reversed.

• Mismatched end links and bracelet: The bracelet and end links should match the reference and period.

• Missing service history or papers: Documents are not essential, but they help confirm the watch's story.

Are there alternatives to a Rolex GMT?

Yes. The Tudor Black Bay GMT, the Omega Seamaster Planet Ocean GMT and Grand Seiko's GMT models all offer a 24-hour hand and an independently adjustable hour hand at different price points.

The Tudor Black Bay GMT, made by Rolex's sister brand, uses an in-house flyback movement and a red-and-blue bezel that recalls the Pepsi. Browse the Tudor Black Bay collection for current examples. Omega's Planet Ocean GMT pairs a dive-watch build with a two-tone 24-hour bezel; see the Omega Seamaster collection. Grand Seiko's GMT models suit buyers who prefer Japanese finishing and a quieter design.

Frequently asked questions

1. What is the main difference between the Rolex GMT-Master and GMT-Master II?

The GMT-Master II has an hour hand that can be set independently in one-hour jumps, while the GMT-Master's hour hand and 24-hour hand are linked. That makes the GMT-Master II quicker to adjust when you travel and lets it show three time zones instead of two.

2. Can you set the hour hand independently on a GMT-Master?

No. On every GMT-Master reference, from the 6542 to the 16700, the 24-hour hand is geared to the hour hand. You read a second time zone by rotating the bezel instead.

3. How many time zones does a Rolex GMT-Master II show?

A GMT-Master II shows three time zones: local time on the hour hand, home time on the 24-hour hand, and a third zone read by rotating the 24-hour bezel.

4. Is the Rolex GMT-Master II worth it?

For a traveler who wants one robust everyday watch, the GMT-Master II is one of the most practical Rolex models, with a ceramic bezel, a 70-hour power reserve, and a true GMT function. Whether it is worth the price depends on the reference and condition you choose.

5. Is the Rolex Pepsi GMT-Master II discontinued?

Yes. Rolex removed the red-and-blue Pepsi GMT-Master II from its catalog at Watches and Wonders in April 2026. Existing examples, including the steel 126710BLRO, are now available only on the pre-owned market.

6. Which Rolex GMT holds its value best?

Steel GMT-Master II references with popular bezels, such as the Pepsi and Batman, have historically held value well, and collectors seek original, unpolished vintage GMT-Masters with full provenance. Past performance does not guarantee future prices.

7. Should I buy a GMT-Master or GMT-Master II?

Choose the GMT-Master II for travel and daily wear, and choose a vintage GMT-Master for history and collector character. If you want both, the neo-vintage GMT-Master II 16710 combines an aluminum bezel with the independent hour hand.

8. Does a pre-owned Rolex GMT come with a warranty?

At LD Time, yes. Watches not covered by a transferable third-party warranty carry our 

one-year limited warranty. Rolex's own five-year guarantee runs from the original date of sale and may not apply to watches bought from an independent dealer.
