Rolex Datejust 31, reference 278383RBR-0013, cased in steel and gold with a 31 mm diameter. The bezel is diamond-set, and the champagne-colour dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside runs the calibre 2236, a self-winding movement certified as a Superlative Chronometer, delivering around 55 hours of power reserve. Central seconds and a date display are both present, along with a screw-down crown for extra security. The watch is set with diamonds, giving it a formal, jewellery-like presence on the wrist. It is fitted on a steel and gold bracelet with a folding Oysterclasp and an Easylink comfort extension link. The screw-down crown helps hold the case to its 100 metre water resistance rating.
