Rolex Lady-Datejust 28 28 mm 279138RBRCRJ Yellow Gold/Diamonds Champagne

The Rolex Lady-Datejust is arguably the most enduring icon in women's fine watchmaking, and the 28mm generation — introduced as a refinement of the earlier 26mm case — strikes the ideal balance between delicate proportions and contemporary legibility. Reference 279138RBRCRJ represents that lineage at its most opulent, pairing an 18k yellow gold case with a factory diamond-set bezel and a richly appointed champagne Roman numeral dial.

At 28mm, the Lady-Datejust 28 sits elegantly on the wrist without overpowering it. The case is crafted entirely in 18k yellow gold, a material Rolex has mastered over decades using its own in-house Rolex Foundry alloy for consistent color and durability. The polished and brushed surfaces interact beautifully with the warm gold tone, making the watch a statement piece even before the eye reaches the dial.

The diamond bezel of the 279138RBRCRJ is set by Rolex's own craftspeople using individually selected brilliant-cut diamonds chosen for cut, color, and clarity. This factory-set bezel is a critical distinction for collectors — it preserves the watch's official Rolex provenance and ensures the diamonds are fitted to the same engineering tolerances as every other component. The result is a bezel that sparkles with uniform intensity all the way around.

The champagne dial with Roman numerals is one of the most sought-after configurations in the Lady-Datejust collection. The warm, golden-toned champagne finish harmonizes perfectly with the yellow gold case, while the Roman hour markers add a classical horological sensibility. The date aperture at 3 o'clock, framed by Rolex's signature Cyclops lens on the sapphire crystal, delivers instant legibility without disrupting the dial's graceful symmetry. Power comes from a Rolex-certified automatic movement, ensuring the accuracy and reliability the brand is world-renowned for. The watch also carries a 100-meter (330-foot) water resistance rating, making it far more capable than its jeweled appearance might suggest.

The five-link Jubilee bracelet — introduced by Rolex in 1945 alongside the original Datejust — is considered the natural companion for this model. In 18k yellow gold it drapes the wrist with a supple, luxurious feel that no aftermarket bracelet can replicate. The Oysterclasp with Easylink comfort extension system (standard on current Lady-Datejust references) provides a secure, refined closure worthy of the watch's overall caliber.
