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

A new Datejust 31 in steel with a black mother-of-pearl dial and diamond setting. Rolex never dyes its mother-of-pearl, so the colour and structure of each dial belongs to the shell it was cut from and no two are alike. The 31 mm Oyster case is waterproof to 100 metres with a Cyclops lens over the date, and the movement is the calibre 2236 with a Syloxi hairspring in silicon.
