Rolex Day-Date 36 mm

Rolex Day-Date 36, reference 128236-0023, measures 36 mm in platinum. The case has a fluted platinum bezel and a screw-down crown, and the dial sits under a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 3255, a self-winding movement certified as a chronometer with a power reserve of approximately 70 hours. The bright blue dial is set with diamonds and shows the day and date along with central seconds. Platinum's weight and softness make it difficult to machine, which is part of why this President bracelet, with its concealed folding Crownclasp, feels so substantial on the wrist. Rolex rates the case to 100 metres of water resistance.
