The Rolex Lady-Datejust reference 279383RBR-0001 is a 28mm luxury timepiece that exemplifies the collection’s blend of elegance and technical precision. This model features a Yellow Rolesor construction, harmonizing a durable 904L Oystersteel case with an 18k yellow gold screw-down winding crown and a fixed bezel set with 46 brilliant-cut diamonds. The sunray champagne dial is adorned with applied yellow gold index hour markers and luminescent hands, all protected by a scratch-resistant sapphire crystal with a Cyclops magnifying lens over the date aperture. It is paired with a five-piece link Jubilee bracelet that integrates a concealed folding Crownclasp for a seamless aesthetic.
At its core, the watch is powered by the COSC-certified caliber 2236, a self-winding mechanical movement that incorporates a patented Syloxi silicon hairspring to ensure high resistance to magnetic fields and temperature variations. This movement provides a power reserve of approximately 55 hours and supports essential timekeeping functions including central hours, minutes, and seconds, alongside an instantaneous date display with rapid setting. The Oyster case is equipped with a Twinlock double waterproofness system, guaranteeing water resistance up to 100 meters, which makes it suitable for both formal occasions and light aquatic activities.
General reviews of the 279383RBR highlight its status as a quintessential dress watch for women, often praised for its refined proportions and the high-contrast brilliance of the diamond-set bezel against the two-tone gold and steel. Collectors and enthusiasts frequently note its exceptional build quality and the reliability of the caliber 2236 movement. While the watch is lauded for its timeless design and versatility as a daily luxury piece, some feedback mentions that the 28mm diameter may feel small compared to modern trends toward larger cases, and its significant market value reflects its position as a high-end investment in the Lady-Datejust lineage.
