Catalogue description
Dealer description — Oliver & Clarke
The Rolex GMT-Master is one of the most historic and iconic watches the brand ever produced. Its origin dates back to a commission request by Pan American World Airways in the early 50’s for their fleet of pilots who needed access to different time zones. These pieces would feature a similar design to another watch that Rolex was developing around that time, the Submariner, but would include a fourth hand running on 24-hr time, and a bi-colored bezel insert to represent AM/PM times. Those colors, naturally, would be the PanAm colors: Red & Blue. Thus, in 1953, the Ref. 6542 GMT-Master was born. These early pieces were ultimately, fragile arguably flawed in some ways, and were therefor succeeded by the updated Reference 1675 in 1959. This Reference introduced a larger case size with crown-guards and a bi-colored blue + red bezel insert made of aluminum. The Ref. 1675 underwent many small changes over its 21-year production run, with a slew of dial, bezel, bracelet, and hand variations. You know, Rolex stuff. And eventually, the 1675 would evolve into the first 5-digit GMT-Master, The Ref. 16750 that we have here. These pieces, at a glance, retain the look and feel like a 1675, but now utilize a 'quickset' date function with the Calibre 3075 movement, and are typically broken down into two difference variants, each with their own appeal. The early pieces feature matte black dials, whereas the second half of production introduced glossy black dials with the first applied Tritium-filled white gold indices. The piece that we have here is the latter, with a glossy black dial. It dates to circa 1985 and remains in strong overall condition, with a thick, symmetrical case that has been lightly previously polished. It shows normal signs of wear throughout with only a few small scattered blemishes. The gloss black dial within has developed a light, even 'stippling' throughout, resulting in an attractive matte appearance with nicely patinated Tritium plots within those white gold applied indices. The Tritium handset also matches beautifully. The bezel exhibits matching wear to the case, and has a correct 'Pepsi' insert with vibrant blue and red colors. It comes fitted to a correct solid-link Oyster bracelet with a signed blade clasp that matches the condition of the case. Overlooked for many years, the Ref. 16750 carries over virtually everything that collectors love about its predecessor, but have that added functionality of a quickset date. And though not exceedingly rare, are certainly not common and can still be had for less than a 1675. Sounds pretty good if you ask us!
Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide
Military, pilot and travel watches
The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.
In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.
What to look for
- Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
- High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
- 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
- Wire lugs on early wristlets converted from pocket watches.
Dating clues
- Wire-lug wristlets: c. 1900–1925.
- Military specifications of the Second World War: 1939–1945.
- GMT and world-time wristwatches: mainly after 1950.
