Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278383RBR-0028, cased in steel and gold at 31 mm across. The case carries a diamond-set bezel and a sapphire crystal with a Cyclops lens over the date. Inside is calibre 2236, a self-winding Perpetual movement with a power reserve of approximately 55 hours, certified as a chronometer. The white mother-of-pearl dial is set with diamonds and paired with central seconds and date functions, and the screw-down crown adds a further layer of security. This is a dress watch built around gem-setting rather than tool-watch function. The steel and gold bracelet closes with a concealed folding Crownclasp. It stays water resistant to a depth of 100 metres.
