Rolex Day-Date 36 mm

The Rolex Day-Date 36 128399TBR-0007 is a white gold watch measuring 36 mm across. The case follows Rolex's Oyster architecture with a monobloc middle case and screw-down winding crown, and the bezel is set with diamonds. Inside is the calibre 3255, a perpetual, self-winding mechanical movement with a power reserve of about 70 hours and Superlative Chronometer certification. A sapphire crystal with a Cyclops lens sits over the date. The blue ombré dial is set with diamonds, and the watch shows both day and date, a function that gives it its name and its status as a chronometer. It is fitted to a President bracelet in white gold with a concealed folding Crownclasp. Rolex rates the case to 100 metres of water resistance.
