A GMT watch tracks two time zones simultaneously — your home time and your travel time. It's one of the most useful complications in watchmaking, and one of the simplest to read.
How it works
The main hour hand shows your local time. A second hand, often tipped with a contrasting colour, completes one rotation every 24 hours and points to a 24-hour scale on the dial or bezel. That second hand stays set to your home time zone, so you always know what time it is back home.
Two places, one wrist. That's the GMT promise.
The Abyss Diver Blue
Our Abyss Diver Blue pairs GMT functionality with 200m water resistance. The unidirectional bezel lets you track elapsed time underwater, while the GMT hand keeps you anchored to home.
