Ref. 278343RBR-0004
This Rolex Datejust 31 mm, reference 278343RBR-0004, is a women's model in steel and gold with a 31 mm case. The domed bezel is set with diamonds, and the dial, also diamond-set in silver, sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding Perpetual movement with a power reserve of approximately 55 hours, and the watch carries chronometer certification. A screw-down crown protects the movement, and the dial shows a central seconds hand alongside the date. The steel and gold bracelet closes with a concealed folding Crownclasp. This is a dress watch built for daily wear rather than display alone. Water resistance reaches 100 metres, a figure well supported by the screw-down crown's double waterproofness system.
