Striking emphasis of its useful indications provides excellent legibility to complement the painstaking precision and outstanding durability in this fantastic timepiece from Rolex which offers all these qualities in a wonderfully down-sized and gorgeously tender appearance for a perfect fit into the Lady-Datejust collection. Encircled by the domed bezel and shielded by the scratch-resistant sapphire crystal with Cyclops lens over the date window at the three o'clock position, the chocolate sunburst dial with luminous hour-markers displays hours and minutes via luminous central hands, as well as central seconds. Beneath lies the COSC-certified 2236 caliber that features bidirectional self-winding via Perpetual rotor and offers approximately 55 hours of power reserve while nested inside a 28mm case. Made of stainless steel and 18K Everose gold, the Oyster case ensures 100m water resistance with its screw-down back and screw-down crown with Twinlock double waterproofness system. The Jubilee bracelet is made of stainless steel and 18K Everose gold, featuring concealed folding Crownclasp.
