Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279178-0001, is cased in 18 ct yellow gold measuring 28 mm across. A fluted bezel in yellow gold frames the champagne-colour dial, and a Cyclops lens sits over the date atop the scratch-resistant sapphire crystal. The movement is the calibre 2236, a perpetual, self-winding mechanical unit with a power reserve of approximately 55 hours, and the watch carries Rolex's chronometer certification. Central seconds and a date display round out the functions, and the screw-down crown adds to the case's construction. The watch is fitted on a President bracelet in solid yellow gold, closed by a concealed folding Crownclasp. This is a dress watch built for both durability and refinement. Water resistance reaches 100 metres, a rating maintained by the screw-down crown itself.
