GMT-Master 16700

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

16700-0001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. Introduced in 1988. Beyond the time it carries a gmt.

Self-winding movement with fixed 24-hour hand and quickset date.
