Rolex Lady-Datejust 28 Everose Rolesor — White Roman Dial with Diamond Bezel | Ref. 279381RBR

Conceived as the companion to the iconic Datejust line but scaled for elegance at 28mm, the Lady-Datejust Reference 279381RBR in Everose Rolesor combines the structural integrity of 904L Oystersteel with the warmth of 18-karat Everose gold in a watch of understated feminine refinement. The 18-karat Everose gold diamond bezel frames a white dial carrying Roman numerals in a classic typographic arrangement — an eternal configuration that has defined the Datejust aesthetic since 1945. The sapphire crystal's Cyclops lens magnifies the date at 3 o'clock for effortless legibility.

Calibre 2236 — developed by Rolex specifically for the Lady-Datejust and Datejust 31 — powers this reference with a silicon Syloxi hairspring that renders the movement impervious to everyday magnetic fields and provides stable rate performance across a wide temperature range. Self-winding via a bidirectional rotor, the movement delivers approximately 55 hours of power reserve and achieves Superlative Chronometer certification, guaranteeing performance to +2/-2 seconds per day — a standard that significantly exceeds COSC requirements for ladies' movements.

The Jubilee bracelet in Everose Rolesor — five-piece links alternating Oystersteel and Everose gold — ensures the watch transitions fluidly from day to evening. The concealed folding Crownclasp secures the bracelet with the precision expected of a Rolex clasp mechanism. Reference 279381RBR is the Lady-Datejust distilled to its essence: technically sovereign, visually timeless, and crafted from materials that will outlast the decades.
