An interesting detail on a Rolex GMT MASTER 16760.
Something I didn't know, till recently.
An almost rail dial in the GMT MASTER!
Here are some pictures to be credited to Lunar Oyster.

Rail Dial: The alignment of the E and Y, and the C and the C. As you can see here. Which is almost perfect.
16760 from 1984.
Best,
Nicolas
