Housed in a 40mm Oystersteel Oyster architecture case featuring a monobloc middle, screw-down case back, and a screw-down Triplock winding crown, this GMT-Master II is built to withstand water pressure to 100 metres. The bidirectional rotatable 24-hour graduated bezel carries a two-colour grey and black Cerachrom insert in ceramic with moulded numerals and graduations, while the scratch-resistant sapphire crystal protects the black dial beneath — equipped with a Chromalight display offering long-lasting blue luminescence for highly legible reading in low light.
Powering the watch is Rolex Calibre 3285, a Manufacture Rolex movement certified as a Superlative Chronometer following both COSC testing and Rolex certification after casing, achieving a precision of -2/+2 seconds per day. The self-winding Perpetual rotor winds bidirectionally, delivering approximately 70 hours of power reserve, while a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers contribute to the movement's resilience. Functions include centre hour, minute, and seconds hands, a 24-hour display, independent rapid-setting of the hour hand for a second time zone, instantaneous date, and stop-seconds for precise time setting.
The watch is worn on an Oystersteel Jubilee bracelet composed of five-piece links and secured by a folding Oysterlock safety clasp with an Easylink 5mm comfort extension link. Reference 126710GRNR-0003 is presented unworn and complete with its Rolex box and Rolex Card 2026.
