Brand new. This model features a black dial and a two-colour Cerachrom bezel insert in red and blue ceramic. Designed to show the time in two different time zones simultaneously during intercontinental flights, the GMT-Master II has come to be recognized for its robustness and versatile appearance. 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, as well as a bidirectional rotatable 24-hour graduated bezel. The distinctively coloured 24-hour hand displays the “home” reference time in a first time zone which can be read on the graduations on the bezel. The traveller’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 travellers to adapt to their new time zone without affecting the precision of their timekeeping. black dial.
