The Rolex Lady-Datejust 28 reference 279384RBR-0017 is a sophisticated 28mm timepiece featuring a White Rolesor construction, which combines a durable Oystersteel monobloc middle case with a solid 18k white gold bezel. This specific model is distinguished by its dark grey sunray-finished dial, often referred to as rhodium, which is set with ten diamonds in 18k gold settings. The fixed bezel is further elevated by an array of approximately 44 to 46 brilliant-cut diamonds, adding a layer of luxury to the classic Oyster architecture. The watch is paired with a five-piece link Jubilee bracelet in Oystersteel, secured by a concealed folding Crownclasp for a seamless aesthetic.
Internally, the timepiece is powered by the manufacture caliber 2236, a self-winding mechanical movement that is a COSC-certified Superlative Chronometer. This movement incorporates a Syloxi silicon hairspring and Paraflex shock absorbers, providing a power reserve of approximately 55 hours and a precision of -2/+2 seconds per day. The watch features center hands for hours, minutes, and seconds, along with an instantaneous date display visible through a Cyclops magnification lens on the scratch-resistant sapphire crystal. With a Twinlock double waterproofness system, the case is rated for water resistance up to 100 meters.
General reviews of the 279384RBR series praise the model for its elegant evolution of the traditional Lady-Datejust, noting that the 28mm size offers a modern yet feminine presence on the wrist. Critics and enthusiasts alike highlight the high level of craftsmanship in the gem-setting and the reliable performance of the caliber 2236 movement. While the watch is widely appreciated for its versatility as both a daily accessory and a formal dress piece, some notes suggest that the diamond-heavy aesthetic may be too pronounced for those seeking a more understated look. Overall, it is regarded as a hallmark of Rolex’s ability to blend jewelry-like finesse with professional-grade engineering.
