Saying that the history of GMT is hard to understand is an understatement. First, it’s important to understand the model, and the poisoner created a simple table that briefly introduces the key models of each time.

It shows that the GMT-MASTER style has an overlap, dividing into two main lines: GMT-MASTER and GMT-MASTER II. Why is there a difference between the first and second generations? The key difference is in the movement, which affects how the watch is used:

The GMT-MASTER model traditionally uses a GMT design (originally, the GMT hand and the hour hand moved together when adjusting the minute hand, and later there was a second stop to adjust the date separately, though the minute hand still had the third stop).

In the eighties, 16750 and 16760 began to show the difference between the first and second generations: unlike the 16750, the 16760 introduced a three-time design (the first three minutes can still be adjusted together with the GMT and hour hands, while the second gear becomes a separate time hand, keeping the GMT hand fixed; the calendar needs to be adjusted slowly using the hour hand).

But the new second generation did not immediately replace the traditional model, so the first generation 16750 was upgraded to 16700, and the second generation 16760 was upgraded to 16710. If you find the model numbers confusing, note the movement change: Cal. 3075-3175 is the first generation, and Cal. 3085-3185-3186 is the second generation.
