Rolex Lady-Datejust 28 mm

The Rolex Lady-Datejust 28 mm, reference 279178-0002, has a 28 mm case in 18 ct yellow gold. The fluted bezel is also gold, a signature touch on this collection. A sapphire crystal with a Cyclops lens sits over the date, and the silver dial is set with diamonds, including a Roman IX marker set with 8 diamonds. Inside is the self-winding calibre 2236, a chronometer-certified movement with a Syloxi hairspring and about 55 hours of power reserve. Central seconds and a screw-down crown round out the functions. The watch is fitted with a President bracelet in 18 ct yellow gold, closed by a concealed folding Crownclasp. The screw-down winding crown helps hold the case to its 100 metre water resistance rating.
