Just had the idea of how to use your diving bezel for a GMT function. Well, it's actually a reminder of the hours to add or subtract from your home time.

You could memorize it like in the pic. Then you just assume that the 12 o'clock position on the dial is your starting point and just turn the bezel to display the amount of hours you need.

Assume the 12 on the dial as "+" so you have to add the hours that are shown on the bezel.
When you wanted to remember how many hours to substract instead of to add, one would assume the 6 on the dial as "-" and start the hour count from there.
Why 12 and 6? Well twelve is above so a + and 6 is below so a -.

Of course it would be easier to just remember the time difference or set your watch but sometimes you are in a hurry and just forget about it or are unsure, so a reminder on your wrist can be useful.
