The Rolex Lady-Datejust reference 279161-0021 is a 28mm luxury timepiece featuring an Everose Rolesor construction, which combines 904L Oystersteel with 18k Everose gold. The watch is distinguished by its white lacquer dial adorned with 18k Everose gold Roman numeral hour markers and a domed bezel. Its Oyster case utilizes a monobloc middle case, a screw-down case back, and a Twinlock double waterproofness system to ensure water resistance up to 100 meters. The timepiece is paired with a five-piece link Jubilee bracelet featuring a concealed folding Crownclasp and includes a scratch-resistant sapphire crystal with a Cyclops lens for date magnification.
The watch is powered by the in-house caliber 2236, a self-winding mechanical movement that provides a power reserve of approximately 55 hours. This COSC-certified movement incorporates a patented Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to maintain a precision of -2/+2 seconds per day. Complications include central hour, minute, and seconds hands, along with an instantaneous date display with rapid setting and stop-seconds for precise time adjustment.
General reviews of the 279161-0021 emphasize its elegant and versatile aesthetic, noting that the combination of steel and rose gold provides a modern yet classic appearance suitable for both formal and daily wear. Owners and critics often highlight the comfort of the Jubilee bracelet and the reliability of the caliber 2236 movement. While the 28mm size is praised for its feminine proportions and traditional appeal, some reviews note that the watch maintains a significant wrist presence due to the luster of the Everose gold accents. Minor criticisms occasionally point to the limited visibility of the movement due to the solid case back, which is a standard design choice for the Oyster Perpetual collection.
