About the Rolex Datejust 279383RBR

The Rolex Datejust 279383RBR is the diamond-set bezel version of the current-generation 28mm Lady-Datejust in Yellow Rolesor, combining Oystersteel with 18k yellow gold and topped with a factory diamond-set bezel in 18k yellow gold. It is the premium diamond-bezel tier of the modern Lady-Datejust 28 family. At WatchGuys, we carry pre-owned and unworn Rolex Datejust 279383RBR examples across the full range of factory diamond dial configurations and both bracelet options. The 279383RBR sits alongside the fluted-bezel Rolex Datejust 279173, the smooth-bezel Rolex Datejust 279160, and the Everose Rolesor 279381RBR diamond-bezel sister in the current Rolex Datejust 28mm lineup.

Rolex Datejust 279383RBR Specifications

The 279383RBR measures 28mm in diameter and is built in Rolex's Yellow Rolesor configuration, with the Oystersteel case middle and outer bracelet links paired with 18k yellow gold on the winding crown, center bracelet links, and the diamond-set bezel. The bezel is set with brilliant-cut diamonds hand-set into individual 18k yellow gold settings around the circumference. The "RBR" suffix in the reference number is Rolex's internal designation for this exact bezel configuration, denoting a diamond-set bezel rather than the fluted bezel of the standard 279173 sibling. Inside is the Caliber 2236, a Superlative Chronometer movement featuring the patented Syloxi silicon hairspring, Paraflex shock absorbers, a 55-hour power reserve, and accuracy of plus or minus 2 seconds per day after casing. The Oyster case is rated to 100 meters of water resistance with a screw-down Twinlock crown and sapphire crystal with the signature Cyclops lens over the date at 3 o'clock. Case thickness is approximately 9.5mm and lug-to-lug is approximately 33mm.

Rolex Datejust 279383RBR Dial Options

The 279383RBR offers one of the most jewelry-leaning dial selections in the entire Lady-Datejust 28 catalog, with most variants featuring factory-set diamonds to match the bezel. The champagne diamond dial is the signature configuration, pairing naturally with yellow gold and exclusive to Yellow Rolesor and full yellow gold Datejust references. It features a warm champagne sunray finish with diamond hour markers set in 18k yellow gold settings and an additional 8 diamonds set into a Roman numeral IX at 9 o'clock. The white mother of pearl dial with factory diamond hour markers is one of the most popular configurations, with each oyster-derived dial showing unique iridescent patterning. Additional choices include the lavender (lilac) diamond dial exclusive to certain Yellow Rolesor configurations, silver diamond dial with diamond markers, and champagne Roman dials with diamond accents. Both bracelet options are produced in matching Yellow Rolesor: the three-link Oyster with folding Oysterclasp and Easylink extension, and the five-link Jubilee with concealed Crownclasp.

Pre-owned Rolex Datejust 279383RBR prices typically range from $15,000 to $20,000 depending on dial, bracelet, condition, and completeness with box and papers.

Rolex Datejust 279383RBR vs. Rolex Datejust 279173

The 279383RBR and the 279173 are the two current-production Yellow Rolesor Lady-Datejust 28 references, and the only difference between them is the bezel. The 279383RBR uses a factory diamond-set 18k yellow gold bezel, set with brilliant-cut diamonds in individual yellow gold settings around the circumference. The Rolex Datejust 279173 uses a fluted 18k yellow gold bezel with the heritage Datejust grooved design. Both share the same 28mm Oystersteel case, the same Caliber 2236 movement, the same Oyster and Jubilee bracelet options, and many of the same dial colors. Dial options on the 279383RBR lean more heavily toward factory diamond hour marker variants to complement the bezel. The 279383RBR typically trades at a $3,500 to $5,000 premium over the 279173 on the secondary market. The Everose Rolesor counterpart to the 279383RBR is the 279381RBR, which trades at a slight premium, reflecting current collector preference for rose gold.

Common Questions

Rolex Datejust 279383RBR FAQ

• What does the RBR suffix mean on the Rolex 279383RBR?

  RBR is Rolex's internal designation for a factory diamond-set bezel on certain Datejust references. On the 279383RBR, the suffix indicates that the bezel is set with brilliant-cut diamonds in 18k yellow gold settings, rather than the fluted bezel found on the standard 279173 sibling. The RBR suffix appears across multiple Lady-Datejust 28 references with diamond bezels, including the 279381RBR in Everose Rolesor and the 279384RBR in steel with a white gold diamond bezel. The diamond layout, settings, and stone quality are all original factory work, not aftermarket additions, and are verified by Rolex hallmarks on the case.

• What size is the Rolex Datejust 279383RBR?

  The Rolex Datejust 279383RBR has a 28mm Oyster case in Yellow Rolesor with a factory diamond-set bezel, a thickness of approximately 9.5mm and a lug-to-lug of about 33mm. It is the smallest current-production Datejust with a factory diamond bezel and the entry size in the modern Lady-Datejust diamond-bezel lineup. The 28mm size works best on wrists from roughly 5 inches to 6.25 inches. For the same diamond-bezel configuration in a larger case, the 31mm Datejust 31 counterpart is the 278383RBR.

• Rolex 279383RBR vs. Rolex 279173, what is the difference?

  The only difference between the Rolex 279383RBR and the Rolex 279173 is the bezel. The 279383RBR uses a factory diamond-set 18k yellow gold bezel, set with brilliant-cut diamonds in individual yellow gold settings around the circumference. The 279173 uses a fluted 18k yellow gold bezel with the heritage Datejust grooved design. Both share the same 28mm Oystersteel case, the same Caliber 2236 movement, and the same Oyster and Jubilee bracelet options. Dial options on the 279383RBR lean more heavily toward factory diamond hour marker variants to complement the bezel. The 279383RBR typically trades at a $3,500 to $5,000 premium over the 279173.

• What dials are available on the Rolex Datejust 279383RBR?

  The 279383RBR offers one of the most jewelry-leaning dial selections in the Lady-Datejust 28 catalog. The champagne diamond dial is the signature configuration, with a warm champagne sunray finish, factory diamond hour markers in 18k yellow gold settings, and an additional 8 diamonds set into a Roman numeral IX at 9 o'clock. The white mother of pearl dial with factory diamond hour markers offers an iridescent, jewelry-leaning alternative. The lavender (lilac) diamond dial is exclusive to certain Yellow Rolesor configurations and is one of the most distinctive options in the lineup. Additional choices include silver diamond, champagne Roman with diamond accents, and black mother of pearl with diamonds.

• How much does a Rolex Datejust 279383RBR cost?

• Is the Rolex 279383RBR a good investment?

  The 279383RBR offers strong long-term value for buyers who want a current-production Rolex with factory diamonds in the most classic two-tone Lady-Datejust configuration. Yellow Rolesor with diamond bezel has been the heritage diamond Datejust look since the mid-twentieth century, and authorized dealer waitlists for specific dial variants such as the lavender diamond and mother of pearl can stretch to 12 months or longer. The pre-owned market consistently trades the 279383RBR at or near retail, with rare dial configurations occasionally appreciating above retail. As with any diamond-set piece, condition of the factory diamonds and originality of the bezel are central to value, and we authenticate both before listing.
