GMT-Master II Watch REFERENCE 126710BLRO MODEL CASE Oyster, 40 mm, Oystersteel BEZEL Bidirectional rotatable 24-hour graduated bezel. Two-colour red and blue Cerachrom insert in ceramic, moulded numerals and graduations WATER-RESISTANCE Waterproof to 100 metres / 330 feet MOVEMENT Perpetual, mechanical, self-winding, GMT function CALIBRE 3285, Manufacture Rolex POWER RESERVE Approximately 70 hours BRACELET Jubilee, five-piece links DIAL Black CERTIFICATION Superlative Chronometer (COSC + certification after casing) 24-Hour Rotatable Bezel This model features a black 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. Black Dial Like all Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, especially in the dark, thanks to its Chromalight display. The broad hands and hour markers, in simple shapes – triangles, circles, and rectangles – are filled with a luminescent material that emits a long-lasting glow. Oystersteel 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 fields such as 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.
