Crafted entirely in 18kt yellow gold, the 28mm Oyster case features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown delivering waterproofness to 100 metres / 330 feet. The scratch-resistant sapphire crystal is fitted with a Cyclops lens over the date aperture, while the bezel hosts 44 brilliant-cut diamonds that frame the dial in continuous brilliance.
The diamond-paved dial is set with 291 diamonds and displays the time via centre hour, minute, and seconds hands alongside an instantaneous date with rapid setting and a stop-seconds function for precise time adjustment. Powering the watch is the Calibre 2236 — a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor, a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, COSC-certified precision of -2/+2 seconds per day after casing, and a power reserve of approximately 55 hours.
The watch rides on the President bracelet in 18kt yellow gold, distinguished by its semi-circular three-piece links and secured by a concealed folding Crownclasp — a pairing that has long defined the Lady-Datejust as one of watchmaking's most recognizable expressions of refined femininity.
