The Rolex Lady-Datejust reference 279383RBR-0012 is a 28mm luxury timepiece that exemplifies the collection’s blend of elegance and technical precision. The case is crafted from Yellow Rolesor, a signature Rolex combination of 904L Oystersteel and 18kt yellow gold. It features a champagne-colored sunray dial adorned with ten diamonds set in 18kt gold settings, ensuring long-lasting luster. The fixed 18kt yellow gold bezel is set with 46 brilliant-cut diamonds, adding a significant jewelry element to the watch. This model is paired with a three-piece link Oyster bracelet that includes a folding Oysterclasp and the Easylink 5mm comfort extension system for adjustable sizing.
Mechanically, the watch is powered by the in-house caliber 2236, a self-winding movement that features a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers. This COSC-certified chronometer offers a precision of -2/+2 seconds per day and a power reserve of approximately 55 hours. In terms of complications, the timepiece provides center hour, minute, and seconds hands, along with an instantaneous date window at the 3 o’clock position, magnified by a Cyclops lens. The Oyster case utilizes a Twinlock double waterproofness system and a scratch-resistant sapphire crystal to provide water resistance up to 100 meters.
General reviews of the 279383RBR highlight its status as a timeless and highly recognizable investment piece. It is frequently praised for its balanced proportions and the graceful way the sunray dial reflects light. Owners often note its versatility, describing it as a sophisticated companion for both formal events and everyday wear.
