Rolex Lady-Datejust 28 mm

Rolex's Lady-Datejust 28 mm, reference 279174-0010, is cased in steel and gold and measures 28 mm across. The fluted bezel is gold, a detail original to the Rolesor construction that pairs steel with gold on this case. A sapphire crystal with a Cyclops lens sits over the date, and the white mother-of-pearl dial is set with diamonds in 18 ct gold settings. Inside is the self-winding calibre 2236, a Rolex manufacture movement certified as a Superlative Chronometer with a power reserve of around 55 hours. The screw-down crown adds security, and the date function runs alongside a centre seconds hand. A steel Oyster bracelet closes with a folding Oysterclasp. Rolex rates the case to 100 metres of water resistance.
