	The 16700 trades as a usable late-vintage GMT-Master, not an auction trophy. Pepsi side carries the classic family look and commands the stronger general-market premium; the black bezel attracts a narrower collector audience that values the quieter late-run alternative. Standard examples cluster GBP 8,000–15,000 / CHF 8,000–15,000 across the major houses depending on dial generation, lume status, and paperwork. The Chuck Yeager / Real McCoy's special edition sits in its own tier above the standard market — the three documented lots all clear well above HK$ 100,000.

The linked-hand mechanism means the local hour hand jumps in one-hour steps when the date is advanced — the original GMT-Master operating feel from the 1950s preserved in a sapphire-crystal modern case.

Caliber 3175 is the final GMT-Master movement — a one-reference caliber exclusive to the 16700. Specifications converge across the published literature and 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-rated, adjusted to 5 positions and temperature.

	The 3175 is the last fixed-GMT movement that did not have an independently adjustable GMT hand. The independently set GMT hour hand belongs to the 3085 (16760, 1983–1989) and the 3185 / 3186 (16710, 1989–2019) — not the 3175. Sotheby's collector guide line about an "independently adjustable flying GMT hand" on the 16700 is a published error rather than an interpretive contradiction; the 16700 caliber 3175 is unambiguously a caller GMT in every primary, secondary, and auction-house source surveyed.

	Antiquorum Lot 88 (Geneva June 2020) documents a 1996 head with a 93150/501B Oyster bracelet. The 93150 is a service or later replacement reference — it became standard on the 16710 — so the bracelet on that lot is service-era rather than original delivery. Period-correct mapping for the article: Oyster 78360 with 501 / 580 end-links throughout the early-to-mid run, Oyster 78790 from late production; 93150 fittings are service-era.
