Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279178-0030, comes in 18 ct yellow gold and measures 28 mm across. The case follows Rolex's Oyster architecture, with a monobloc middle case and a screw-down crown and back. A fluted bezel in yellow gold sits around the white dial, which is protected by a scratch-resistant sapphire crystal with a Cyclops lens over the date. Inside is the calibre 2236, a self-winding mechanical movement certified as a Superlative Chronometer, with a power reserve of approximately 55 hours. Central seconds and an instantaneous date with rapid setting complete the functions. The watch is fitted with a Jubilee bracelet in yellow gold, closed by a concealed folding Crownclasp. The screw-down Twinlock crown helps keep the case watertight to 100 metres.
