GMT Watches

The GMT watch is brilliant, not because of its complexity but because of its simple ingenuity. Because the movement's going train (primary series of gears) in a conventional watch is made to spin the hour hand around the dial every 12 hours, all that is required to become a GMT tracker is simply a second hour hand geared to run half as fast and an additional 24-hour time scale. In other words, the 24-hour hand circles the dial once a day instead of twice, its tip pointing to the corresponding hour, leaving no confusion as to whether it’s a.m. or p.m.

While GMT watches were first created for pilots and are historically linked to aviation, they have since taken on a reputation as an adventurer’s watch, useful for the traveler who wants to touch down in another timezone and have his watch keep track of his departure destination.
