Rolex 279139RBR Price
At Watch My Diamonds, the Rolex Lady-Datejust 279139RBR is available at $59,650.
Every 279139RBR on this page is unworn. Rolex releases the solid white gold Lady-Datejust in small numbers and the dial variants rarely overlap, so availability here moves reference by reference rather than as a single stocked model. Where a listing carries no figure, that reference is available on request.
About the Rolex Lady-Datejust 279139RBR
The 279139RBR is the solid white gold, diamond-bezel version of the Lady-Datejust 28. Rolex introduced the 279 series in 2018 to replace the outgoing 179 line, moving the Lady-Datejust to a 28 mm Oyster case and a new-generation movement. The reference itself carries the specification: 279 for the 28 mm Lady-Datejust, 139 for solid 18k white gold, and the RBR suffix that Rolex uses for a factory diamond-set bezel.
The case is 18k white gold with a screw-down crown and 100 metres of water resistance. Inside is Rolex’s self-winding Caliber 2236 with the Syloxi silicon hairspring, certified as a Superlative Chronometer and rated to roughly 55 hours of running time. Every example listed here is fitted to the President bracelet in matching white gold with the concealed Crownclasp.
Rolex 279139RBR — Frequently Asked Questions
What size is the Rolex Lady-Datejust 279139RBR?
28 mm. The 279 series is the Lady-Datejust 28. It is easy to confuse with the 31 mm Datejust, which carries 278 and 178 reference numbers instead.
What does the RBR suffix mean?
RBR marks the factory diamond-set bezel. The same case with a smooth or fluted bezel carries a different suffix, so an RBR reference is always the diamond version rather than an aftermarket setting.
Is the 279139RBR solid gold?
Yes. The 139 in the reference denotes solid 18k white gold throughout — case, bezel and President bracelet. It is not a two-tone Rolesor model, which is what the 384 and 173 references indicate.
Which dials come on the 279139RBR?
Rolex has offered the reference with opal, mother-of-pearl and diamond-set dials. The examples listed on this page are the -0002 and -0004 pink opal dials and the -0008 white mother-of-pearl.
What movement does the 279139RBR use?
Caliber 2236, the self-winding movement Rolex built for the 28 mm Lady-Datejust. Its Syloxi hairspring is silicon rather than metal, which makes it less sensitive to magnetic fields than the movement it replaced.
