Rolex has chosen to introduce its very first ceramic dial on an 18 ct white gold version of the Oyster Perpetual GMT-Master II.
In the same material, with the same green colour and the same lustre, this Cerachrom dial and the daytime half of the green and black bezel insert echo each other perfectly.
Calibre 2236
The Datejust 31 is equipped with calibre 2236, a movement entirely developed and manufactured by Rolex. A distillation of technology, this self-winding mechanical movement delivers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.
Calibre 2236 is equipped with a self-winding system via a Perpetual rotor and offers a power reserve of approximately 55 hours.
The Oyster case, symbol of waterproofness
A paragon of robustness and elegance, the 31 mm Oyster case of the Datejust 31 is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case of the version presented is crafted from a solid block of 18 ct yellow gold. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal, which features a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.
