24-Hour Rotatable Bezel

This model features a meteorite dial and a two-colour Cerachrom bezel insert in red and blue ceramic. In addition to conventional hour, minute, and seconds hands, the GMT-Master II features an arrow-tipped hand, which circles the dial once every 24 hours, along with a bidirectional rotatable 24-hour graduated bezel. The distinctively coloured 24-hour hand displays the “home” reference time in the first time zone, which can be read on the bezel graduations.

The traveler’s local time is easily set by “jumping” from hour to hour, thanks to an ingenious mechanism operated via the winding crown: the hour hand can be adjusted forwards or backwards independently of the minute and seconds hands. This allows travelers to adapt to their new time zone without affecting the precision of their timekeeping.
