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

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 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 follows the long 1675 run and is the first GMT-Master with a five-digit reference number. It is generally dated to the early 1980s through 1988, when the [[Reference:16700|16700]] continued the caller GMT with a sapphire crystal and caliber 3175.

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.

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: the 24-hour hand sits above the hour hand, followed by the minute and seconds hands. 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.

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.

The auction record shows a wide spread by condition, dial, provenance, and whether a lot includes its original accessories. The table is a record of individual lots, not a price guide for every 16750. Khanjar examples should be compared only with other documented government-logo dials, since a single estimate or result does not establish a general market tier.
The table records individual lots. Results and estimates vary with condition, dial originality, provenance, accessories, and venue; they are not a current price guide. Government-logo examples require comparison with other documented watches rather than a general market tier.
