Description

The Rolex Lady-Datejust 28 reference 279458RBR-0001 is presented in an Oyster case measuring 28 mm, crafted in 18 ct yellow gold and richly adorned with diamonds. The model’s monobloc middle case, screw-down case back, and Twinlock winding crown are employed to ensure the integrity of the Oyster architecture, while water resistance is rated to 100 metres (330 feet). A scratch-resistant sapphire crystal is fitted, with a Cyclops lens placed over the date for enhanced legibility. Around the case, a bezel set with 44 brilliant-cut diamonds is showcased, and the case sides and lugs are further embellished with diamonds to heighten radiance.

Within, the Manufacture Rolex Calibre 2236 is installed—a perpetual, mechanical, self-winding movement adjusted to a precision of −2/+2 seconds per day after casing. Centre hours, minutes, and seconds are displayed, and an instantaneous date with rapid setting is provided, with stop-seconds included for precise time adjustment. A Syloxi silicon hairspring with patented geometry is employed for stability, while high-performance Paraflex shock absorbers are fitted to enhance robustness. Bidirectional self-winding via the Perpetual rotor is used, delivering a power reserve of approximately 55 hours.

A diamond-paved dial is presented, set with 291 diamonds to create a luminous field upon which time is read with effortless clarity. The watch is completed by a President bracelet in 18 ct yellow gold with three-piece solid links, set with 596 brilliant-cut diamonds. A concealed folding Crownclasp is integrated to preserve a seamless, jewelry-like aesthetic.

Through the union of advanced Rolex chronometry and exquisite gem-setting, the 279458RBR-0001 is positioned as a pinnacle expression of the Lady-Datejust—where reliability, precision, and opulence are harmoniously combined.
