The Rolex Lady-Datejust 28 reference 279384RBR-0013 is a refined 28mm luxury timepiece that utilizes White Rolesor, a signature Rolex combination of high-strength Oystersteel and 18k white gold. This model features a dark grey sunray dial with a characteristic glow that shifts based on light reflection, complemented by 18k white gold index hour markers with luminous fill. The watch is distinguished by its fixed 18k white gold bezel set with 46 brilliant-cut diamonds. It is paired with a five-piece link Jubilee bracelet crafted from Oystersteel, featuring a concealed folding Crownclasp for a seamless aesthetic.

Internally, the timepiece is powered by the COSC-certified caliber 2236, a self-winding mechanical movement manufactured by Rolex. This movement incorporates a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to ensure precision and reliability, offering a power reserve of approximately 55 hours. Complications are focused on essential timekeeping, including center hour, minute, and seconds hands, along with an instantaneous date display visible through a Cyclops lens at the 3 o’clock position. The Oyster case is equipped with a Twinlock double waterproofness system, guaranteeing water resistance up to 100 meters.

General reviews of the 279384RBR series emphasize its classic elegance and status as a versatile accessory suitable for both formal and daily wear. The transition to the 28mm case size from previous 26mm versions has been praised for providing a more contemporary presence while maintaining feminine proportions. While the diamond-set bezel is frequently cited as a highlight for its craftsmanship and “sparkling symphony” of light, some enthusiasts note that the lack of an adjustable extension on the concealed Crownclasp means the fit must be precisely sized during initial setup. Overall, it is regarded as a premier example of functional jewelry that maintains the rigorous technical standards of the Rolex brand.
