Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278274-0026, comes in steel and gold with a 31 mm case. The fluted bezel is gold, and a screw-down crown protects the case. The dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the self-winding calibre 2236, a chronometer with a power reserve of approximately 55 hours. The aubergine dial is set with diamonds and shows a central seconds display alongside the date. The watch is fitted on a steel bracelet closed by a concealed folding Crownclasp. That screw-down crown, along with the case construction, keeps the watch waterproof to 100 metres.
