	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 [[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.

	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.		Caliber 3075 is the main mechanical change over the 1575GMT.

The listed 28.5mm diameter and 6.2mm thickness are movement specifications, not case measurements.

	~~The~~ hand~~-setting~~ stack ~~differs from~~ the 1575GMT; ~~movement references describe~~ the 24-~~hour~~ hand ~~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.		Specialist movement diagrams describe a revised hand stack compared with the 1575GMT; the reference still uses the linked-hand caller-GMT arrangement.

	The 3075 gives way to caliber 3175 in the 16700 from 1988 to 1999.

Four 16750 examples are known carrying the Royal Oman Police emblem in white print, all sharing 7.6 million serials and all missing the inside-caseback serial repeat, which points to a single batch produced concurrently for one commission.

	Caliber 3075 is the ~~headline upgrade~~ over the 1575GMT it replaces. It carries 27 jewels, beats at 28,800 vph against the old 19,800, holds a 48-hour reserve, and adds hacking seconds and a quickset date through the crown, all on a free-sprung Microstella balance with a Breguet overcoil. The movement measures 28.5mm across and 6.2mm thick. Some movement registries quote a reserve nearer 50 hours; 48 is the more conservative figure.

	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).		The hand-setting stack also changed from the 1575GMT.

	Service-replacement dials surface frequently, and the "Swiss-only" dial is the most common pattern: a later Luminova-or-tritium dial carrying only "Swiss" at the bottom in place of the original "T SWISS T" tritium wording.

	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.

	Quickset date, higher beat rate, and hacking seconds all make the 16750 more modern than a 1675, 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 and read as vintage next to the sapphire-and-flyer 16710 that follows the 16760.

	The 3075 gives way to the 3175 in the 16700 from 1988 to 1999, a one-reference caliber that keeps the caller mechanic with minor revisions. Service-era swaps from 3075 to 3175 do circulate. The two 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~~.

	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 a poor proxy for original delivery, since the 1980s service window covers most surviving 16750s and bracelet swaps were common.		Surviving examples wear both options.

	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 their dial-side originality intact sit at the top of the standard market. The Omani Police Khanjar variant sits above all of it.		The 16750 trades as a usable late-vintage GMT-Master.
