Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278288RBR-0024, is cased in 18 ct yellow gold measuring 31 mm across. A sapphire crystal with a Cyclops lens covers the date, and the bezel is set with diamonds around an olive green dial that carries diamonds of its own. The self-winding calibre 2236 drives the watch, a Superlative Chronometer movement with around 55 hours of power reserve. Central seconds and a date display sit alongside a screw-down crown, part of the watch's Oyster architecture. This is a chronometer finished with a President bracelet in yellow gold, secured by a concealed folding Crownclasp. The screw-down crown holds the case to its 100 metre rating.
