Rolex GMT-Master II 40mm in Oystersteel with a black dial

The Oyster Perpetual GMT-Master II in Oystersteel with a black dial and a Oyster bracelet.

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.

Like all Rolex Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display.

The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.
