24-Hour Rotatable Bezel<\/h2>\n

This model features a black dial and a two-colour Cerachrom bezel insert in blue and black 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, as well as a bidirectional rotatable 24-hour graduated bezel. The distinctively coloured 24-hour hand displays the \u201chome\u201d reference time in a first time zone which can be read on the graduations on the bezel. The traveller\u2019s local time is easily set by \u201cjumping\u201d 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.<\/p>\n<\/div>\n<\/div>\n

Black dial<\/h2>\n

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 \u2013 triangles, circles, rectangles \u2013 are filled with a luminescent material emitting a long-lasting glow.<\/p>\n<\/div>\n<\/div>\n

Oystersteel<\/h2>\n

Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.<\/p>\n<\/div>\n<\/div>\n
