At 28 mm, the Lady-Datejust wears with quiet refinement. The Oyster case is constructed from White Rolesor, blending Oystersteel with white gold, and features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial easy to read at a glance.
The dark grey dial is set with Roman numeral hour markers, lending a classic character to the piece. Beneath the crystal, Rolex Caliber 2236 — a perpetual, mechanical, self-winding movement — delivers a precision of -2/+2 seconds per day after casing, a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, and a power reserve of approximately 55 hours via bidirectional winding through the Perpetual rotor. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The three-piece solid-link Oyster bracelet in Oystersteel fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link, allowing for easy on-the-fly adjustment. Reference 279174-0014 is a considered choice for those drawn to the enduring language of the Lady-Datejust.
