The first watch Rolex ever built for airline pilots, and one of its most copied designs since. Launched in 1955 for Pan Am flight crews, the GMT-Master carries a fourth hand and a 24-hour bezel so the wearer can track two time zones at once. Bakelite turned to aluminum, steel split from gold and two-tone, and the GMT-Master became the GMT-Master II when the local hour hand learned to move on its own. Color branches — Pepsi, Root Beer, Coke, black — ended up carrying as much collector weight as the reference numbers themselves.
The GMT-Master is Rolex's wristwatch for reading two time zones, introduced in 1955 and later adopted by Pan Am. Its extra hand turns once every 24 hours against a rotating bezel. On the original GMT-Master, that hand stays linked to the ordinary hour hand; rotating the bezel sets the second time-zone reading.
 
Rolex introduced the GMT-Master II in 1982. Its local-hour hand adjusts independently in one-hour steps, leaving the minutes and 24-hour hand undisturbed. Reference guides place the GMT-Master end around 1999–2000; the GMT-Master II then became the sole line. Ceramic bezels joined the GMT-Master II in 2005.

The experimental years. The case had no crown guards, the 24-hour bezel was moulded from bakelite and cracked easily, and a gold branch with alpha hands ran alongside the red-and-blue (Pepsi) steel watch. Most surviving examples carry later service inserts, because the original bakelite was fragile enough to rarely survive daily wear.
The [[Reference:6542|6542]] has no crown guards. Its translucent bezel insert, usually called Bakelite in auction catalogues, carries the 24-hour scale. Steel examples have a red-and-blue insert; gold examples include brown inserts and alpha-shaped hands. Replacement aluminium inserts occur on surviving watches, so bezel material alone does not establish original delivery.

Caliber labels vary in early cataloguing. Phillips identifies caliber 1066 in a gold 6542 dated 1959; Christie's records it in a steel example dated around 1958. The exact changeover dates between these calibers remain uncertain.

The reference that turned the GMT-Master from an experiment into an institution. Crown guards arrived with the [[Reference:1675|1675]], along with an aluminum bezel insert (replacing the fragile bakelite) and a twenty-year production run long enough to hold several distinct watches under one number. Early pointed crown guards, known as PCG, gave way to rounded guards; gilt dials gave way to matte; and the steel watch was joined by a gold branch and a two-tone Root Beer branch.
The steel [[Reference:1675|1675]] added crown guards and an aluminium bezel insert. Pointed guards gave way to rounded ones, and the dial changed from gilt printing on a glossy surface to white printing on matte black. Early gold 1675s had no crown guards; Christie's dates their addition to 1967. Steel-and-gold versions followed in the early 1970s.

The five-digit quick-set era on the GMT-Master side of the family split. Caliber 3075 added a quick-set date and a higher beat rate but kept the older linked-hand GMT logic, in which the 24-hour hand tracks the local hour hand rather than moving on its own. Acrylic crystals held through most of the run. The branch map also gets busier here, with steel, two-tone, and solid-gold references all in production at once.
Caliber 3075 added a directly adjustable date while retaining the linked hour and 24-hour hands. The steel [[Reference:16750|16750]] and two-tone [[Reference:16753|16753]] use acrylic crystals. The gold [[Reference:16758|16758]] has sapphire. Monochrome and Sotheby's date the steel reference's introduction to 1980; ''The Vintage Rolex Field Manual'' uses 1979.

The functional break in the family. Caliber 3085 in the [[Reference:16760|16760]] introduced an independently adjustable local hour hand, which turned the 24-hour bezel into a third-time-zone tool rather than a second-time-zone aid. The thick transitional [[Reference:16760|16760]] gave way to the slimmer [[Reference:16710|16710]] in 1989, and the line spent nearly two decades on that reference before the ceramic era rewrote the watch.
The [[Reference:16760|16760]] introduced caliber 3085 and the independently adjustable local-hour hand. Its thicker case accounts for the collector names Fat Lady and Sophia Loren. The original bezel was red and black, commonly called Coke. Rolex dates the GMT-Master II launch to 1982; reference guides variously begin the 16760's production range in 1982 or 1983.
 
The slimmer [[Reference:16710|16710]] followed with caliber 3185 and a choice of red/blue, red/black or black inserts. Two-tone [[Reference:16713|16713]] and gold [[Reference:16718|16718]] versions used the same basic movement arrangement. The date is corrected by moving the local-hour hand through midnight, without a separate direct date quick-set.

Phillips documents a steel 16710 with caliber 3186 and papers dated 2008, after the steel ceramic successor appeared in 2007. Its dial has the separate vertical strokes called a stick dial. That lettering also occurs with caliber 3185, so the movement needs direct identification.

The last reference on the original side of the family split. Sapphire crystal, caliber 3175, and a choice of Pepsi or black bezel. The 16700 kept the older linked-hand GMT logic rather than adopting the independent hour hand of the GMT-Master II references it ran in parallel with, which is the mechanical distinction that kept the two lines separate right to the end.
The [[Reference:16700|16700]] was the last GMT-Master. It combined a sapphire crystal and caliber 3175 with the original linked-hand arrangement, and was sold alongside the GMT-Master II. It retained a direct quick-set date.

Rolex listed the 116758 SARU separately from the 116758 SA and SANR. Its catalogues describe a 40mm yellow-gold case with 76 diamonds and a bezel set with 23 diamonds, 18 rubies and 18 sapphires. In 2012 Rolex listed black- and pavé-dial configurations, bracelet 78208, and an optional 728-diamond bracelet 74768. Auction catalogues attribute both Cal. 3185 and Cal. 3186 to dated examples; the reference article records the disagreement.

Cerachrom is Rolex's name for its ceramic bezel material. The yellow-gold [[Reference:116718LN|116718LN]] introduced it to the GMT-Master II in 2005. Steel-and-yellow-gold Rolesor followed in 2006, then steel in 2007. All five references below use caliber 3186.

The steel [[Reference:126710BLRO|126710BLRO]] brought a ceramic red-and-blue bezel to steel in 2018, initially on Jubilee. Everose and steel/Everose models appeared the same year, followed by further bezel colours and the left-crown versions.

Quick-set date and independent local-hour adjustment are different functions. A GMT-Master with caliber 3075 or 3175 can advance the date directly. On a GMT-Master II, the date follows the jumping local-hour hand through midnight. Rolex's user guide describes that method separately from setting the minutes and 24-hour hand.

Recurring branch identities run across the reference numbers and sometimes matter more than the digits themselves. The red-and-blue Pepsi bezel starts with the steel [[Reference:6542|6542]] and has stayed the default visual identity of the line ever since. The brown-and-gold Root Beer bezel begins on the two-tone 1675/3 and gold 1675/8 in the early 1970s, then carries forward into the [[Reference:16753|16753]], [[Reference:16758|16758]], [[Reference:16713|16713]], and the brown side of the [[Reference:16718|16718]]. The red-and-black Coke bezel arrives with the first GMT-Master II, the [[Reference:16760|16760]], and stays associated mainly with that reference and the early [[Reference:16710|16710]]. Gold and two-tone GMT-Masters are part of the family from the earliest production onward, not a late luxury afterthought.
Pepsi means red and blue; Coke means red and black. Root Beer is used for brown and gold vintage combinations and, more loosely, the modern brown-and-black Everose models. These are collector names. They do not identify a reference, case metal or original bezel by themselves.
 
The same red-and-blue ceramic colour scheme appears on both steel and white-gold watches. Brown inserts also span several gold and two-tone generations. Case material, dial and movement are needed alongside the bezel colour to identify a watch.

The GMT-Master market rewards different habits than the Submariner market, even when the watches overlap in period. The Submariner collects around case shape, military use, and dial text. The GMT-Master collects just as much around bezel color, travel mythology, and branch identity.
Original delivery, period-correct fitment and later service replacement are separate claims. A clasp code dates the clasp. It cannot establish the date of the watch head or prove that the bracelet was delivered with it. An auction photograph shows the configuration at the time of sale; original fitment needs further evidence.
 
The [[Reference:gmt-master-ii-5digit-ceramic-family|116xxx ceramic family]] and [[Reference:gmt-master-ii-6digit-family|126xxx ceramic family]] have separate guides. Both use six-digit numerical references; the distinction is between movement generations.

The same caution comes up again and again across the family. Original delivery is not the same thing as period-correct fitment, and a watch that wears period parts correctly today may never have left the factory that way. Bracelet dates date the bracelet, not the watch head. Service inserts are common on every reference and nearly universal on the earliest ones, where the bakelite originals rarely survived. Nickname language is useful shorthand, but Pepsi, Coke, Root Beer, and plain black each cover a range of dial and bezel variants, and the labels can flatten real differences if used too loosely.

Vintage Rolex GMT-Master advertisement
Vintage Rolex GMT-Master advertisement

The GMT-Master is Rolex's wristwatch for reading two time zones, introduced in 1955 and later adopted by Pan Am. Its extra hand turns once every 24 hours against a rotating bezel. On the original GMT-Master, that hand stays linked to the ordinary hour hand; rotating the bezel sets the second time-zone reading.

Rolex introduced the GMT-Master II in 1982. Its local-hour hand adjusts independently in one-hour steps, leaving the minutes and 24-hour hand undisturbed. Reference guides place the GMT-Master end around 1999–2000; the GMT-Master II then became the sole line. Ceramic bezels joined the GMT-Master II in 2005.

Common entry points

Vintage GMT-Master
1675
The steel reference spans pointed and rounded crown guards, gilt and matte dials. Gold and two-tone versions have their own case and dial changes.
Aluminium-bezel GMT-Master II
16710
Red/blue, red/black or black inserts and an independently adjustable local-hour hand. Some late watches have caliber 3186; dial lettering alone does not identify the movement.
Steel ceramic GMT-Master II
116710LN
Introduced in 2007 with caliber 3186 and a black Cerachrom insert. The dial has green GMT-Master II lettering and a green 24-hour hand.

Early GMT-Master (1955–1959)

The 6542 has no crown guards. Its translucent bezel insert, usually called Bakelite in auction catalogues, carries the 24-hour scale. Steel examples have a red-and-blue insert; gold examples include brown inserts and alpha-shaped hands. Replacement aluminium inserts occur on surviving watches, so bezel material alone does not establish original delivery.

Reference Approximate period Movement Case Bezel Distinction
6542 1955–1959 1030-family GMT calibers, including 1036, 1065 and 1066 About 38mm; steel or 18k yellow gold Translucent plastic insert; later metal replacements also found No crown guards

Caliber labels vary in early cataloguing. Phillips identifies caliber 1066 in a gold 6542 dated 1959; Christie's records it in a steel example dated around 1958. The exact changeover dates between these calibers remain uncertain.

GMT-Master 1675 (1959–1980)

The steel 1675 added crown guards and an aluminium bezel insert. Pointed guards gave way to rounded ones, and the dial changed from gilt printing on a glossy surface to white printing on matte black. Early gold 1675s had no crown guards; Christie's dates their addition to 1967. Steel-and-gold versions followed in the early 1970s.

Reference Approximate period Movement Case Versions Distinction
1675 c.1959–1980 1565 GMT; later 1575 GMT About 40mm; steel, yellow gold or steel/yellow gold Steel; 1675/8 gold; 1675/3 two-tone Case and dial changes differ by metal

Transitional GMT-Master (1979–1988)

Caliber 3075 added a directly adjustable date while retaining the linked hour and 24-hour hands. The steel 16750 and two-tone 16753 use acrylic crystals. The gold 16758 has sapphire. Monochrome and Sotheby's date the steel reference's introduction to 1980; The Vintage Rolex Field Manual uses 1979.

Reference Approximate period Movement Case Dial and bezel options Distinction
16750 Around 1980–1988 3075 40mm steel Matte or glossy dial; red/blue or black insert Direct quick-set date; acrylic crystal
16753 Around 1980–late 1980s 3075 40mm steel and 18k yellow gold Brown or black dial and bezel variants Two-tone GMT-Master with direct quick-set date
16758 Around 1980–late 1980s 3075 40mm 18k yellow gold Brown or black dial and bezel variants Gold GMT-Master with sapphire crystal

GMT-Master II (1982–2007)

The 16760 introduced caliber 3085 and the independently adjustable local-hour hand. Its thicker case accounts for the collector names Fat Lady and Sophia Loren. The original bezel was red and black, commonly called Coke. Rolex dates the GMT-Master II launch to 1982; reference guides variously begin the 16760's production range in 1982 or 1983.

The slimmer 16710 followed with caliber 3185 and a choice of red/blue, red/black or black inserts. Two-tone 16713 and gold 16718 versions used the same basic movement arrangement. The date is corrected by moving the local-hour hand through midnight, without a separate direct date quick-set.

Reference Approximate period Movement Case Bezel options Distinction
16760 1982/1983–c.1988 3085 40mm steel Red/black First GMT-Master II; thicker case
16710 c.1989–2007; later dated examples recorded 3185; some late examples with 3186 40mm steel Red/blue, red/black or black Slimmer case than the 16760
16713 Late 1980s–mid-2000s 3185 40mm steel and 18k yellow gold Brown/gold or black Two-tone GMT-Master II
16718 Late 1980s–mid-2000s 3185 40mm 18k yellow gold Brown or black Solid-gold GMT-Master II

Phillips documents a steel 16710 with caliber 3186 and papers dated 2008, after the steel ceramic successor appeared in 2007. Its dial has the separate vertical strokes called a stick dial. That lettering also occurs with caliber 3185, so the movement needs direct identification.

Late GMT-Master (1988–1999)

The 16700 was the last GMT-Master. It combined a sapphire crystal and caliber 3175 with the original linked-hand arrangement, and was sold alongside the GMT-Master II. It retained a direct quick-set date.

Reference Approximate period Movement Case Bezel options Distinction
16700 c.1988–1999 3175 40mm steel Red/blue or black Sapphire crystal; linked hour and 24-hour hands

Gem-set GMT-Master II 116758 SARU

Rolex listed the 116758 SARU separately from the 116758 SA and SANR. Its catalogues describe a 40mm yellow-gold case with 76 diamonds and a bezel set with 23 diamonds, 18 rubies and 18 sapphires. In 2012 Rolex listed black- and pavé-dial configurations, bracelet 78208, and an optional 728-diamond bracelet 74768. Auction catalogues attribute both Cal. 3185 and Cal. 3186 to dated examples; the reference article records the disagreement.

116758 SARU Introduced around 2006; Rolex catalogue entries in 2008 and 2012 3185 and 3186 attributed in auction catalogues 40mm 18k yellow gold; diamond-set case and sapphire/ruby/diamond bezel Black and pavé dials; bracelets 78208 and optional 74768

See the 116758 SARU reference guide for the source-by-source dates, movement attributions and variant limits.

Ceramic GMT-Master II 116xxx (2005–2019)

Cerachrom is Rolex's name for its ceramic bezel material. The yellow-gold 116718LN introduced it to the GMT-Master II in 2005. Steel-and-yellow-gold Rolesor followed in 2006, then steel in 2007. All five references below use caliber 3186.

Ceramic GMT-Master II 126xxx (2018 onward)

Caliber 3285 arrived in this generation with an approximately 70-hour power reserve. The steel 126710BLRO brought a ceramic red-and-blue bezel to steel in 2018, initially on Jubilee. Everose and steel/Everose models appeared the same year, followed by further bezel colours and the left-crown versions.

Robb Report reported the withdrawal of both Pepsi references, 126710BLRO and 126719BLRO, from Rolex's catalogue in April 2026. Manufacture and retail-sale dates can differ from catalogue dates.

Movement progression

Quick-set date and independent local-hour adjustment are different functions. A GMT-Master with caliber 3075 or 3175 can advance the date directly. On a GMT-Master II, the date follows the jumping local-hour hand through midnight. Rolex's user guide describes that method separately from setting the minutes and 24-hour hand.

Caliber Setting arrangement References
1036 / 1065 / 1066 Linked hour and 24-hour hands; no direct date quick-set 6542
1565 GMT / 1575 GMT Linked hour and 24-hour hands; no direct date quick-set 1675
3075 Linked hour and 24-hour hands; direct date quick-set 16750, 16753, 16758

Bezel colours and case metals

Pepsi means red and blue; Coke means red and black. Root Beer is used for brown and gold vintage combinations and, more loosely, the modern brown-and-black Everose models. These are collector names. They do not identify a reference, case metal or original bezel by themselves.

The same red-and-blue ceramic colour scheme appears on both steel and white-gold watches. Brown inserts also span several gold and two-tone generations. Case material, dial and movement are needed alongside the bezel colour to identify a watch.

Collecting context

Original delivery, period-correct fitment and later service replacement are separate claims. A clasp code dates the clasp. It cannot establish the date of the watch head or prove that the bracelet was delivered with it. An auction photograph shows the configuration at the time of sale; original fitment needs further evidence.

The 116xxx ceramic family and 126xxx ceramic family have separate guides. Both use six-digit numerical references; the distinction is between movement generations.
