Datejust 31, Steel and Yellow Gold, Black Mother-Of-Pearl, Diamond

A Datejust 31 in Yellow Rolesor — Oystersteel with 18 ct yellow gold — carrying a black mother-of-pearl dial with diamond-set hour markers in 18 ct gold settings. Rolex uses mother-of-pearl in its natural colour, so each dial reads differently as the light moves. The 31 mm Oyster case is waterproof to 100 metres, with calibre 2236 inside and about 55 hours of power reserve.
