	The 16700 is a caller GMT. The 16760 (cal. 3085) and the 16710 (cal. 3185 / 3186) are flyer GMTs~~, and~~ the distinction ~~splits~~ the ~~family cleanly~~.		The 16700 is a caller GMT. The 16760 (cal. 3085) and the 16710 (cal. 3185 / 3186) are flyer GMTs. That is the practical distinction between the two movement layouts.

	On a caller GMT the hour and 24-hour hands remain linked. The 3175’s direct quick-set date is separate from GMT hand adjustment, and the second zone is read with the bidirectional 24-hour bezel. On a flyer GMT the 24-hour hand turns independently once per day, while the local hour hand jumps in one-hour increments without disturbing minutes or seconds. The bezel can then be used for a third zone.		On a caller GMT the hour and 24-hour hands remain linked.

	Caliber 3175 is the last movement used in the original GMT-Master line and is associated with the 16700 alone. Published specifications and auction catalogues give it 31 jewels, 28,800 vph (4 Hz), about 48 hours of power reserve, hacking seconds, a quickset date, a Breguet hairspring, a Glucydur balance with Microstella screws, Kif shock protection, COSC certification, and adjustment to five positions and temperature.

	The 3175 does not have an independently adjustable GMT hand. That feature belongs to the 3085 in the 16760 (1983–1989) and to the 3185 / 3186 in the 16710 (1989–2007). Some auction descriptions use loose GMT terminology, so identify the movement and hand-setting behavior on the watch itself.		The 3175 does not have an independently adjustable GMT hand.

Some auction descriptions use loose GMT terminology, so identify the movement and hand-setting behavior on the watch itself. A 2025 Sotheby’s collector guide describes the 16700 as having an independent flying GMT hand, which conflicts with its own distinction between the 16700 and 16710 and with the cited movement references. The linked-hand description used here follows the 3175 specifications and the 16750/16710 comparison evidence.

	The 3175 supersedes the 3075 of the 16750 and ends the linked-hand GMT line. Its production span is the 16700's alone: 1988 to 1999.		The 3175 supersedes the 3075 of the 16750 and ends the linked-hand GMT line. Its production span is the 16700's alone: 1988 to 1999.

	The bezel is a bidirectional 24-hour aluminium insert, catalogued in two colourways: Pepsi (red and blue) and all-black. Pepsi ~~dominates~~ the ~~surviving population~~. Coke inserts in red and black do turn up on 16700s, but the configuration was never catalogued for the reference, so those are aftermarket fittings or service swaps.

	Caliber 3175 is the last GMT-Master movement and the only one Rolex built for a single reference. The specification is consistent across the published literature and the major-house lot catalogues: 31 jewels, 28,800 vph (4 Hz), 48-hour power reserve, hacking seconds, quickset date, Breguet hairspring, Glucydur balance with Microstella screws, Kif shock protection, COSC chronometer certification, adjusted to five positions and temperature.

	What the 3175 lacks is an independently adjustable GMT hand. That belongs to the 3085 in the 16760 (1983–1989) and to the 3185 / 3186 in the 16710 (~~1989–2019~~). Sotheby's collector guide describes an "independently adjustable flying GMT hand" on the 16700; the line is an error in print, and every other documented account has the 3175 working as a caller GMT.

	Service history is worth checking on watches from the end of the run. Antiquorum Lot 88 recommends "an overhaul at buyer's expense" and Sotheby's Lot 10 records "very minute corrosion spots" on the movement, which together suggest intervention is common on late-1990s examples. How often Rolex service fitted a 3185 in place of a 3175 during an overhaul is not documented anywhere in print. Since the 3175 shared no parts with the parallel 16710, a swap of that kind would have to be a deliberate movement replacement.		Service history is worth checking on watches from the end of the run.

	The 16700 is the last classic GMT-Master, the final reference built around the synchronized "caller" 24-hour hand. Production ran from 1988 to 1999, and for most of that time the 16700 sat in the catalogue beside the GMT-Master II 16710 (1989–2007). Caliber 3175 was made for this reference and no other, running 31 jewels at 28,800 vph with a 48-hour reserve, hacking seconds, quickset date, adjustment to five positions and temperature, and COSC certification. The one branch with a market of its own is the Chuck Yeager / Real McCoy's special edition of 1997, fifty pieces with the caseback engraved "General Chuck Yeager, Bell X-1, October 14th 1947".
