Rolex Datejust 31 mm

The Rolex Datejust 31 mm, reference 278344RBR-0012, comes in a case of steel and gold measuring 31 mm across. The domed bezel is set with diamonds, and the dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding mechanical movement with a power reserve of approximately 55 hours, certified as a chronometer. The watch shows the date and central seconds, and its screw-down crown seals the case against moisture and dust. Gemstones appear on the bezel, giving the case its sparkle. A steel bracelet with a concealed folding Crownclasp completes the piece. It stays water resistant to a depth of 100 metres.
