Rolex GMT Master 16700
Rolex GMT Master 16700 is the last GMT Master produced by Rolex from 1988 (serial n. R7*) to 1999, always with caliber 3175. In the same period, Rolex produced the second version of GMT Master: ref 16710.
It's the first GMT Master marketed with sapphire crystal.

What's the difference between GMT Master 1 and 2?
In thouse years, Rolex proposed on the market two different GMT watches: GMT Master and GMT Master 2. The first one can detect two different time zones (using the big arrow and the rotating bezel), but GMT Master 2 can show three different time zones (the hour hand can jump one hour per time to detect another time zone).
