Full 18k Everose gold from case to clasp, a diamond-set bezel, and the President bracelet — the 279135RBR is the Lady-Datejust in its most dressed-up configuration. At 31mm with a brown sunburst dial, this reference carries the “RBR” suffix that denotes a factory diamond bezel: a full circle of individually set stones replacing the traditional fluted or smooth ring. It is a women’s Datejust built entirely around the interplay of warm gold tones and white brilliance.

The 279135RBR Up Close: Case, Dial and Bracelet
The diamond bezel is the centerpiece. Each stone is set into a channel around the full circumference of the 18k Everose gold ring, creating an unbroken band of light that elevates this Lady-Datejust above fluted or smooth-bezel alternatives. The 31mm case — the classic women’s Datejust diameter since the model’s introduction — is fully Everose gold with a screw-down caseback and Twinlock crown for 100 meters of water resistance despite the precious materials.
The brown sunburst dial shifts from deep chocolate at the edges to a lighter honey tone at center under different angles. Applied Roman numeral or baton markers (depending on dial variant) carry a thin layer of luminescent material. The President bracelet — semi-circular three-piece links in full Everose gold — is the most formal bracelet Rolex produces, closing with a concealed Crownclasp that maintains a seamless link profile on the wrist. This reference is part of the Lady-Datejust collection.
Movement Options: Swiss vs Japanese
Rolex introduced a dedicated women’s caliber for the 31mm Lady-Datejust line, and the Swiss option here reflects that specific architecture rather than a downsized men’s movement.
- Swiss Automatic — Mirrors the Caliber 2236: 28,800 vph, approximately 55-hour power reserve (Syloxi silicon hairspring, a material Rolex developed specifically for enhanced precision and magnetic resistance), hacking seconds, quickset date. The 2236 was purpose-built for the 31mm case — thinner and more compact than the 3235 used in larger models.
- Japanese Automatic — Miyota-based movement with automatic winding, hacking seconds, quickset date, and approximately 40-hour reserve. A reliable and cost-effective option that any independent watchmaker can service, well-suited to everyday wear.
Both movements wind automatically through the Perpetual rotor. The Swiss variant offers a longer power reserve and silicon hairspring technology specific to the Caliber 2236 specification.
