Rolex 3175

Probable

The caliber of the 16700, the last GMT-Master before the line consolidated on the GMT-Master II. It retains the geared 24-hour hand, so a 16700 does NOT have an independently settable hour hand — a point routinely got wrong in listings that treat the two model names as interchangeable.
