The Rolex Lady-Datejust reference 279139RBR-0008 is a 28mm luxury timepiece crafted from 18k white gold. This model features a white mother-of-pearl dial, which is naturally unique for each watch, adorned with ten diamonds set in 18k gold settings to ensure lasting luster. The case is topped with a fixed bezel set with 44 brilliant-cut diamonds and is paired with a three-piece link President bracelet that features a concealed folding Crownclasp. A scratch-resistant sapphire crystal with a Cyclops lens protects the dial, while a screw-down Twinlock crown helps ensure water resistance up to 100 meters.
Internally, the watch is powered by the in-house caliber 2236, a self-winding mechanical movement that provides a power reserve of approximately 55 hours. The movement includes a Syloxi hairspring in silicon for increased stability against temperature variations and high-performance Paraflex shock absorbers. In terms of complications, the timepiece provides center hours, minutes, and seconds, along with an instantaneous date window at the 3 o’clock position and stop-seconds for precise time setting.
General reviews of this reference emphasize its blend of jewelry-like elegance and robust mechanical engineering. The combination of the white gold construction and the diamond-set bezel is often praised for its refined aesthetic, while the 28mm case size is noted for its suitability for smaller wrists. Owners frequently highlight the comfort and seamless look of the President bracelet. While recognized as a premier investment-grade heirloom, some observers note that its highly decorative nature and use of precious materials make it a more formal choice compared to stainless steel alternatives.
