With the new Lady-Datejust models bringing aesthetic evolution to the series, along with enhanced performance and durability, they represent a perfect complement to the Day-Date collection, especially with the President or, as in this particular model, Jubilee bracelet. The automatic perpetual 2236 caliber is entirely manufactured by Rolex and certified by COSC. Along with bi-directional winding via Perpetual rotor, it also features a Rolex-patented Syloxi hairspring, which significantly improves the regularity of the oscillator and the precision of the watch. On the subtle silver dial hours, minutes and seconds are shown by center hands, while instantaneous date is shown in an aperture at the three o'clock position. The 18K yellow gold Oyster case measures 28mm in diameter and features fluted bezel as well as scratch-resistant sapphire crystal with a Cyclops lens for the date aperture. It is waterproof to 100m due to the twinlock double waterproofness system of the screw-down crown and monobloc middle case, as well as the hermetic screw-down case back. The case is mounted onto 18K yellow gold Jubilee bracelet with five-piece links and a concealed folding Crownclasp.
