<small>[[Reference:gmt-master|GMT-Master]] › '''16750'''</small>


The [[Reference:16750|16750]] is the first five-digit GMT-Master and the bridge between the 1675 and the 16760 / 16710 generation. Caliber 3075 raised the beat rate from 19,800 to 28,800 vph and added quick-set date, but the older caller-GMT mechanic stayed: the 24-hour hand tracks the local hour hand, the second time zone reads off the rotating bezel. The acrylic crystal stayed too. The result is a watch that lives mechanically halfway between the 1675 it replaced and the sapphire-era GMTs that followed.

The 16750 is the first five-digit GMT-Master and the predecessor to the 16700. Caliber 3075 raised the beat rate to 28,800 vph and added a quick-set date while retaining the linked-hand caller-GMT: the 24-hour hand follows the local hour hand and the bezel sets the second zone. The steel reference kept an acrylic crystal; the gold 16758 used sapphire.

The 16750 follows the long 1675 run and is the first GMT-Master with a five-digit reference number. It runs for eight years and ends in 1988, the same year the [[Reference:16760|16760]] retires. The 16760 brings the independent local hour hand and the flyer-GMT mechanic; the 16750 keeps the older linked-hand caller mechanic that defines the original GMT-Master line. The 16700 takes the caller mechanic forward into 1999 with the sapphire crystal and the slightly different caliber 3175.
The 16750 follows the long 1675 run and is the first GMT-Master with a five-digit reference number. It ends in 1988, when the [[Reference:16700|16700]] takes the caller GMT forward with a sapphire crystal and caliber 3175. The [[Reference:16760|16760]] was a parallel GMT-Master II from 1983 to 1988; it introduced the independent local-hour hand and the flyer-GMT mechanic while the 16750 kept the linked-hand layout.


The 16750 is more modern than a 1675 — quickset date, higher beat rate, hacking — but mechanically it still behaves like a GMT-Master rather than a GMT-Master II. The acrylic crystal and the 40mm crown-guard case look modern next to the 1675 but read as vintage next to the sapphire-and-flyer 16710 that follows the 16760.
The quick-set date, higher beat rate, and hacking seconds update the 1675 design without changing its caller-GMT operation. The acrylic crystal and 40mm crown-guard case separate the steel 16750 from the sapphire case used on the gold 16758 and later references.

== Production outline ==
== Production outline ==


Production ran approximately 1981 to 1988 across the dominant editorial reading. A specialist split surfaces on the launch year — some specialist sources push it back to 1979 or 1980. The earliest primary-document anchor is a 27 April 1981 retailer receipt accompanying a documented full-set Bonhams lot in 2024. Catalogued examples dated 1980 surface in the auction record (Sotheby's 2020 lot 109), so the 1980 reading is not unsupported, but the bulk of surviving examples date 1981 onward.
Production is usually dated approximately 1980 to 1988, although sources differ on whether the first examples belong to 1979, 1980, or 1981. Sotheby's dates the introduction of caliber 3075 to 1980; Bonhams documents a 27 April 1981 retailer receipt, and Sotheby's has catalogued an example dated circa 1980. Those records establish the period without proving a single first-serial boundary.


No published Rolex production figure surfaces in the surveyed sources. The eight-year run versus the 1675's twenty-one years implies meaningfully smaller volume — collectors describe the 16750 as "particularly scarce" against the 1675, with matte-dial examples covering only roughly the first four to five years of the run.
No published Rolex production figure surfaces in the documented sources. Matte dials are generally associated with the earlier part of the run, while glossy white-gold-surround dials appear by the mid-1980s; service replacements and overlapping dated examples make a strict year cut unsafe.

Caliber 3075 is the headline upgrade over the 1575GMT it replaces. Specifications: 27 jewels, 28,800 vph (up from 19,800 vph), 48-hour power reserve, hacking seconds, quickset date through the crown. Free-sprung Microstella balance with Breguet overcoil. 28.5mm diameter, 6.2mm thick. Some specialist movement registries quote ~50-hour reserve; the 48-hour figure is the more conservative reading.
Caliber 3075 is the main mechanical change over the 1575GMT. Reference guides and auction descriptions give 27 jewels, 28,800 vph, hacking seconds, and a quick-set date. Published movement tables commonly quote a reserve around 48 hours, while some registries round it nearer 50; the page does not treat either figure as a watch-specific test. The listed 28.5mm diameter and 6.2mm thickness are movement specifications, not case measurements.


The hand-setting stack also changed from the 1575GMT — on the 3075 the order reads hour, GMT, minute, second from the centre post outward. Despite the higher beat rate and the quickset date, the 3075 retains the linked-hand caller-GMT mechanic. The 24-hour hand cannot be set independent of the local hour hand on the 16750. That step waited for the 3085 in the 16760 (1983) and the 3185 in the 16710 (1989).
Specialist movement diagrams describe a revised hand stack compared with the 1575GMT; the reference still uses the linked-hand caller-GMT arrangement. The 3075 retains the linked-hand caller-GMT mechanic, so the 24-hour hand cannot be set independently on a 16750. The independent local-hour hand arrived with caliber 3085 in the 16760 and continued with caliber 3185 in the 16710.


The 3075 is succeeded directly by the 3175 in the 16700 (1988–1999) — a one-reference caliber that retains the caller mechanic with minor revisions. Service-era movement swaps from 3075 to 3175 do circulate; the calibers do not behave identically across hand-setting and date-setting directions, and a 3175 in a 16750 case is a service replacement rather than original fitment.
The 3075 gives way to caliber 3175 in the 16700 from 1988 to 1999. A 3175 in a 16750 case is a service or replacement movement unless the watch has documentation explaining the change; movement and case numbers need to be checked together.

Two dial generations cleanly mapped. The transition is overlapping rather than a hard cutover — 1984 examples surface in both matte and glossy finishes, so the year is the overlap zone rather than a clean hand-off.
The two dial generations overlap in dated examples. Examples dated 1984 surface in both matte and glossy finishes, which makes that year the crossover zone.

Matte black ground with painted indices, no white-gold surrounds. Closest visual link to the late-1675 dial. Tritium luminous compound across the run. The matte 16750 is the watch most likely to be misidentified at a glance as a late 1675; the caliber 3075's hand-stack order and the case-back interior reference number are the cleanest tells.
The matte dial is a black ground with painted indices and no white-gold surrounds. It carries the late-1675 look, but a dial alone does not authenticate the reference. The caliber 3075's hand stack, the case reference and serial, and the crystal should be checked together.

Glossy black lacquer with applied indices in white-gold surrounds. The surface treatment marks the modernization of the dial face — the same WG-surround applied-index format that runs forward into the 16760 and 16710. Tritium continues across this generation; the lume colour is consistent with the matte production and the same period mid-1980s tritium ageing pattern.
Glossy black lacquer carries applied indices in white-gold surrounds, a layout also used on the 16760 and 16710. The cited period examples use tritium, but service dials and later replacements can change the lume material.

Not a separate factory variant. Hairline cracks form in the glossy lacquer over time — a manufacturing defect of the lacquer formulation Rolex used for the white-gold-surround dials before later reformulations. Affected dials were often replaced under service, so survivors with intact spider crazing carry a collector premium for original-dial integrity. The collector view of the pattern splits — some read it as patina, some as damage.
Spider is collector shorthand for the hairline cracking seen in some glossy lacquer dials. It is a condition of the dial surface, not a separate Rolex reference or documented factory option. A cracked dial may be original, refinished, or later replaced; the pattern needs to be assessed with the printing, lume, hands, case, and service history.

A small group of early glossy dials omit the word "Date" above "GMT-Master" at six o'clock. The variant belongs inside the early glossy branch rather than as a separate dial era. The omitted-Date layout is a documented sub-variant rather than a misprint.
A small group of early glossy dials are documented without the word "Date" above "GMT-Master" at six o'clock. The omission is a useful dial variant to record, but its exact production boundary is not established.

The case is the standard 40mm Oyster with crown guards. The acrylic crystal — with the magnifying Cyclops over the date — is the cleanest single-glance separator from the sapphire-era GMTs that follow. The 100m water-resistance rating carries the 1675 specification forward unchanged.
The case is the standard 40mm Oyster with crown guards. The acrylic crystal, with its magnifying Cyclops over the date, separates the steel 16750 from the sapphire-era GMTs that follow. Water resistance was revised to 100m, twice the 50m rating generally given for the four-digit GMT-Master references.


The bezel is a bidirectional 24-hour aluminium insert. Pepsi and all-black are the only factory configurations on the steel 16750 — Coke (red and black) is a 16760 trait and not a documented 16750 option. Insert-back colour is not a clean dating tell on its own; early matte watches sometimes carry red-back inserts, later examples more often blue-back or service-era replacements.
The bezel is a bidirectional 24-hour aluminium insert. Published factory examples use Pepsi or all-black inserts. The black-and-red Coke insert is associated with the 16760; a Coke insert on a 16750 needs fitment and service evidence. Insert-back colour is not a dating rule on its own because replacements circulate.

Period-correct delivery is the 78360 Oyster with 580 endlinks. Jubilee 62510H with 501 endlinks is the optional configuration. Earlier 580 endlinks are shared across the Submariner 5512 / 5513 / 1680 / 16800, Explorer 1016, and GMT-Master 1675 / 16750. Bracelet originality on a 16750 needs case-and-clasp-date verification rather than relying on the endlink stamp alone.
Published period examples appear on the 78360 Oyster with 580 endlinks and on Jubilee 62510-family bracelets with 501 endlinks. A bracelet code dates the bracelet, not the watch head; originality needs case, clasp, endlink, and service-history checks.


Surviving examples wear both options. Matte Pepsi watches turn up on Jubilee more often than the glossy / black-bezel side; black and glossy-spider examples lean Oyster. Fitment as found at auction is not a reliable proxy for original delivery — the 1980s service window covers most surviving 16750s and bracelet swaps were common.
Both bracelet families occur in surviving examples. Auction fitment is a poor proxy for original delivery because service and bracelet swaps were common during the reference's life.

A small Sultanate-of-Oman commission carries the Khanjar emblem at six o'clock above the depth wording. The variant is one of the rarest 16750 sub-types in the auction record. A Bonhams 2021 New Bond Street lot (Bonhams 26687/68, c.1983) carried estimate GBP 70,000–100,000; the catalog noted that a comparable example sold the prior year had a serial number 53 positions away, supporting concurrent-issue production for a single Sultanate commission. Phillips Hong Kong XI 2020 lot 1009 added a parallel anchor: four 16750 examples are known carrying the Royal Oman Police emblem in white print, all sharing 7.6 million serials and missing the inside-caseback serial repeat — consistent with concurrent batch production for a single commission. Khanjar 16750s sit in their own collector tier above the standard market.
A small group of 16750 dials carries the white Royal Oman Police emblem at six o'clock. Phillips describes four known examples, all in the 7.6 million serial range and reportedly from one batch without the repeated serial inside the caseback. Those are auction-house and specialist observations, not a Rolex production statement. The Bonhams and Phillips lots document the branch; they do not establish a complete population or a universal premium.

=== Service-replacement examples ===
=== Service-replacement examples ===


Service-replacement dials surface frequently. A "Swiss-only" service dial — replacing the original "T SWISS T" tritium wording with a later Luminova-or-tritium dial bearing only "Swiss" at the bottom — is the most common pattern. Service-era movement swaps from caliber 3075 to caliber 3175 also circulate. A 16750 case-back with the reference and case number is original; mid-case serials and movement numbers far apart in production date suggest one or both have been replaced. A documented Bonhams Hong Kong 2019 lot (case R672618, movement number 1,828,172) sits well outside the period 0,3xx,xxx-range 3075 movement numbers and reads as a service-replaced example.
[[File:Ref 16750 black-service.webp|thumb|right|280px|alt=Black-bezel service 16750|Black-bezel service 16750]]
Service-replacement dials occur, including later dials marked only "Swiss" in place of the original "T SWISS T" wording. Service-era movement swaps from caliber 3075 to caliber 3175 also occur; the case, movement, dial, and service records should be read together.
 
Caseback and mid-case markings help establish what is present, but neither proves that every component is original. A wide gap between the case serial and movement number is a lead to investigate, not proof of a replacement by itself. The Bonhams Hong Kong 2019 lot with case R672618 and movement number 1,828,172 is an example of an auction-catalogued service-replacement movement, not a universal dating rule.

The combination of glossy white-gold-surround indices, omitted "Date" wording, and web-like lacquer cracking on the same dial is the strongest single signal of an original late-run 16750 dial. Refinishes and service dials rarely carry any of those three traits in isolation, and almost never all three at once.
The combination of glossy white-gold-surround indices, omitted "Date" wording, and lacquer cracking can be a useful lead when assessing a late-run 16750 dial. It is not proof of originality; refinishing, replacement parts, and later service work still need to be ruled out.

The 16750 trades as a usable late-vintage GMT-Master rather than an auction trophy. Standard examples cluster GBP 8,000–15,000 / CHF 9,000–18,000 across the major houses depending on dial generation, lume status, and paperwork. Matte Pepsi examples in clean original condition carry the transitional-watch premium. Glossy spider dials with intact dial-side originality sit at the top of the standard market — original spider crazing reads as a positive collector signal because affected dials were so often replaced under service. The Omani Police Khanjar variant sits in its own tier above all of the above.
The auction record varies with condition, dial, provenance, and original accessories. The table records individual lots rather than a price guide for every 16750. Khanjar examples should be compared with other documented government-logo dials; a single estimate or result does not establish a general market tier.

GMT-Master › 16750

Acrylic, linked-hand GMT
Acrylic, linked-hand GMT

The 16750 is the first five-digit GMT-Master and the predecessor to the 16700. Caliber 3075 raised the beat rate to 28,800 vph and added a quick-set date while retaining the linked-hand caller-GMT: the 24-hour hand follows the local hour hand and the bezel sets the second zone. The steel reference kept an acrylic crystal; the gold 16758 used sapphire.

Where it sits in the line

The 16750 follows the long 1675 run and is the first GMT-Master with a five-digit reference number. It ends in 1988, when the 16700 takes the caller GMT forward with a sapphire crystal and caliber 3175. The 16760 was a parallel GMT-Master II from 1983 to 1988; it introduced the independent local-hour hand and the flyer-GMT mechanic while the 16750 kept the linked-hand layout.

The quick-set date, higher beat rate, and hacking seconds update the 1675 design without changing its caller-GMT operation. The acrylic crystal and 40mm crown-guard case separate the steel 16750 from the sapphire case used on the gold 16758 and later references.

Production outline

Production is usually dated approximately 1980 to 1988, although sources differ on whether the first examples belong to 1979, 1980, or 1981. Sotheby's dates the introduction of caliber 3075 to 1980; Bonhams documents a 27 April 1981 retailer receipt, and Sotheby's has catalogued an example dated circa 1980. Those records establish the period without proving a single first-serial boundary.

No published Rolex production figure surfaces in the documented sources. Matte dials are generally associated with the earlier part of the run, while glossy white-gold-surround dials appear by the mid-1980s; service replacements and overlapping dated examples make a strict year cut unsafe.

Movement notes

Caliber 3075 in 16750
Caliber 3075 in 16750

Caliber 3075 is the main mechanical change over the 1575GMT. Reference guides and auction descriptions give 27 jewels, 28,800 vph, hacking seconds, and a quick-set date. Published movement tables commonly quote a reserve around 48 hours, while some registries round it nearer 50; the page does not treat either figure as a watch-specific test. The listed 28.5mm diameter and 6.2mm thickness are movement specifications, not case measurements.

Specialist movement diagrams describe a revised hand stack compared with the 1575GMT; the reference still uses the linked-hand caller-GMT arrangement. The 3075 retains the linked-hand caller-GMT mechanic, so the 24-hour hand cannot be set independently on a 16750. The independent local-hour hand arrived with caliber 3085 in the 16760 and continued with caliber 3185 in the 16710.

The 3075 gives way to caliber 3175 in the 16700 from 1988 to 1999. A 3175 in a 16750 case is a service or replacement movement unless the watch has documentation explaining the change; movement and case numbers need to be checked together.

Dial map

The two dial generations overlap in dated examples. Examples dated 1984 surface in both matte and glossy finishes, which makes that year the crossover zone.

Matte (early, ~1981–1985)

Matte-dial Pepsi 16750
Matte-dial Pepsi 16750

The matte dial is a black ground with painted indices and no white-gold surrounds. It carries the late-1675 look, but a dial alone does not authenticate the reference. The caliber 3075's hand stack, the case reference and serial, and the crystal should be checked together.

Glossy white-gold-surround (~1986 onward)

Glossy black lacquer carries applied indices in white-gold surrounds, a layout also used on the 16760 and 16710. The cited period examples use tritium, but service dials and later replacements can change the lume material.

Spider crazing

Glossy spider dial 16750
Glossy spider dial 16750

Spider is collector shorthand for the hairline cracking seen in some glossy lacquer dials. It is a condition of the dial surface, not a separate Rolex reference or documented factory option. A cracked dial may be original, refinished, or later replaced; the pattern needs to be assessed with the printing, lume, hands, case, and service history.

No-Date wording variant

A small group of early glossy dials are documented without the word "Date" above "GMT-Master" at six o'clock. The omission is a useful dial variant to record, but its exact production boundary is not established.

Case, bezel, crystal, and crown

The case is the standard 40mm Oyster with crown guards. The acrylic crystal, with its magnifying Cyclops over the date, separates the steel 16750 from the sapphire-era GMTs that follow. Water resistance was revised to 100m, twice the 50m rating generally given for the four-digit GMT-Master references.

The bezel is a bidirectional 24-hour aluminium insert. Published factory examples use Pepsi or all-black inserts. The black-and-red Coke insert is associated with the 16760; a Coke insert on a 16750 needs fitment and service evidence. Insert-back colour is not a dating rule on its own because replacements circulate.

Bracelets, end links, clasps, and packaging notes

Published period examples appear on the 78360 Oyster with 580 endlinks and on Jubilee 62510-family bracelets with 501 endlinks. A bracelet code dates the bracelet, not the watch head; originality needs case, clasp, endlink, and service-history checks.

Both bracelet families occur in surviving examples. Auction fitment is a poor proxy for original delivery because service and bracelet swaps were common during the reference's life.

Special branches

Omani Police (Khanjar)

16750 with Royal Oman Police emblem dial
16750 with Royal Oman Police emblem at 6 o'clock, one of four documented examples in the same 7.6M serial batch

A small group of 16750 dials carries the white Royal Oman Police emblem at six o'clock. Phillips describes four known examples, all in the 7.6 million serial range and reportedly from one batch without the repeated serial inside the caseback. Those are auction-house and specialist observations, not a Rolex production statement. The Bonhams and Phillips lots document the branch; they do not establish a complete population or a universal premium.

Service-replacement examples

Black-bezel service 16750
Black-bezel service 16750

Service-replacement dials occur, including later dials marked only "Swiss" in place of the original "T SWISS T" wording. Service-era movement swaps from caliber 3075 to caliber 3175 also occur; the case, movement, dial, and service records should be read together.

Caseback and mid-case markings help establish what is present, but neither proves that every component is original. A wide gap between the case serial and movement number is a lead to investigate, not proof of a replacement by itself. The Bonhams Hong Kong 2019 lot with case R672618 and movement number 1,828,172 is an example of an auction-catalogued service-replacement movement, not a universal dating rule.

Glossy spider with no-Date wording

The combination of glossy white-gold-surround indices, omitted "Date" wording, and lacquer cracking can be a useful lead when assessing a late-run 16750 dial. It is not proof of originality; refinishing, replacement parts, and later service work still need to be ruled out.

The auction record varies with condition, dial, provenance, and original accessories. The table records individual lots rather than a price guide for every 16750. Khanjar examples should be compared with other documented government-logo dials; a single estimate or result does not establish a general market tier.
