Rolex 1036

Probable

The original GMT caliber. Its 24-hour hand is fixed to the hour hand rather than independently adjustable — the second time zone is read by rotating the bezel, not by setting the hand. That is the defining functional characteristic of every GMT-Master caliber up to the 3085, and testing it is the fastest way to establish which generation of GMT is in front of you.
