About the Rolex Datejust 278383RBR

The Rolex Datejust 278383RBR is the diamond-set bezel version of the current-generation 31mm Datejust 31 in Yellow Rolesor, combining Oystersteel with 18k yellow gold and topped with a factory diamond bezel of 46 brilliant-cut diamonds in 18k yellow gold. At WatchGuys, we carry pre-owned and unworn Rolex Datejust 278383RBR examples across the full range of factory diamond dial configurations and both bracelet options. The 278383RBR sits at the premium tier of the modern Rolex Datejust 31 family, alongside the Everose Rolesor diamond-bezel Rolex Datejust 278381RBR and the fluted-bezel Rolex Datejust 278273 sibling in the same metal.

Rolex Datejust 278383RBR Specifications

The 278383RBR measures 31mm 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 factory diamond bezel holds 46 round brilliant-cut diamonds in 18k yellow gold settings. 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 278273 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.

Rolex Datejust 278383RBR Dial Options

The 278383RBR is offered in one of the most jewelry-leaning dial selections in the entire Datejust 31 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. The olive green floral motif dial and olive green Roman dial with diamond markers and a large diamond-set VI are among the most distinctive options Rolex currently produces, and both pair exceptionally well with yellow gold. Additional choices include white and black mother of pearl with factory diamond hour markers, silver dials with diamond markers, dark grey Roman dials with diamond markers, and white Roman dials for buyers who want the diamond bezel without diamond dial markers. 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.

Rolex Datejust 278383RBR vs. Rolex Datejust 278381RBR

The 278383RBR and the 278381RBR are the two two-tone Datejust 31 references in current production fitted with a factory diamond bezel, and the only difference between them is the gold type. The 278383RBR uses 18k yellow gold (Yellow Rolesor), producing the classic warm gold tone that has defined the two-tone Datejust look since the 1930s. The Rolex Datejust 278381RBR uses 18k Everose gold (Everose Rolesor), Rolex's proprietary rose gold alloy with platinum content that locks in a softer pink hue. Both share the same 31mm Oystersteel case construction, the same 46-diamond bezel layout, the same Caliber 2236 movement, and the same Oyster and Jubilee bracelet choices. Dial options differ to complement each metal: the 278383RBR offers champagne, olive green Roman, and olive green floral dials exclusive to Yellow Rolesor, while the 278381RBR offers aubergine and chocolate dials exclusive to Everose. The 278383RBR typically trades at a small discount to the 278381RBR, reflecting current collector preference for rose gold. For the fluted-bezel alternative in the same Yellow Rolesor configuration, see the Rolex Datejust 278273, which trades at a meaningful discount.

Common Questions

Rolex Datejust 278383RBR FAQ

• What does the RBR suffix mean on the Rolex 278383RBR?

  RBR is Rolex's internal designation for a factory diamond-set bezel on certain Datejust references. On the 278383RBR, the suffix indicates that the bezel is set with 46 round brilliant-cut diamonds in 18k yellow gold, rather than the fluted bezel found on the standard 278273 sibling. The RBR suffix appears across multiple Datejust 31 references with diamond bezels, including the 278381RBR in Everose Rolesor and the 278384RBR in steel with a white gold diamond bezel. The diamond layout, settings, and stone quality are all original factory work, not aftermarket additions.

• How many diamonds are on the Rolex 278383RBR bezel?

  The Rolex Datejust 278383RBR bezel is set with 46 round brilliant-cut diamonds, each hand-set in individual 18k yellow gold settings around the circumference of the bezel. Rolex uses only IF (internally flawless) to VVS-grade diamonds with a minimum of G color on its factory-set pieces. Dial-mounted diamonds on the champagne diamond, mother of pearl, olive green Roman, and silver dial variants are additional to the 46 stones on the bezel and follow the same quality standards.

• Rolex 278383RBR vs. Rolex 278381RBR, what is the difference?

  The only difference between the Rolex 278383RBR and the Rolex 278381RBR is the gold type. The 278383RBR uses 18k yellow gold for a classic warm gold tone (Yellow Rolesor). The 278381RBR uses 18k Everose gold for a softer, contemporary pink tone (Everose Rolesor). Both share the same 31mm Oystersteel case, the same 46-diamond bezel layout, the same Caliber 2236 movement, and the same Oyster and Jubilee bracelet options. Dial options differ to complement each metal. The 278383RBR typically trades at a slight discount to the 278381RBR, reflecting current collector preference for rose gold.

• What dials are available on the Rolex Datejust 278383RBR?

  The 278383RBR offers one of the most jewelry-leaning dial selections in the Datejust 31 catalog. The champagne diamond dial is the signature configuration, pairing naturally with yellow gold and exclusive to Yellow Rolesor configurations. The olive green Roman dial with diamond markers and a diamond-set VI, and the olive green floral motif dial, are among the most distinctive options Rolex produces. Additional choices include white and black mother of pearl with diamond hour markers, silver dials with diamond markers, dark grey Roman dials with diamond markers, and white Roman dials. Most factory configurations include diamond hour markers to coordinate with the bezel.

• How much does a Rolex Datejust 278383RBR cost?

  Pre-owned Rolex Datejust 278383RBR prices typically range from $17,500 to $24,000 depending on dial, bracelet, condition, and completeness.

• Is the Rolex 278383RBR a good investment?

  The 278383RBR offers strong long-term value for buyers who want a current-production Rolex with factory diamonds in the most classic two-tone Rolex 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 olive green Roman diamond and mother of pearl can stretch to 12 months or longer. The pre-owned market consistently trades the 278383RBR 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.
