Rolex Datejust 31 mm

Rolex's Datejust 31 mm, reference 278275-0039, comes in 18 ct rose gold. The case measures 31 mm across and carries a fluted bezel in the same gold. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal, and the screw-down crown adds to the watch's construction. Inside is the self-winding calibre 2236, a chronometer movement with a power reserve of approximately 55 hours. The silver dial is set with diamonds, and the watch shows a central seconds display alongside the date. It is fitted to a rose gold President bracelet with a concealed folding Crownclasp. That crown, doubling as a Twinlock seal, keeps the case water resistant to 100 metres.
