About the Rolex Lady-Datejust 31 278381RBR
The Lady-Datejust is Rolex's dedicated women's interpretation of the Datejust, a line introduced in 1945 as the world's first self-winding waterproof wristwatch with an automatically changing date. The 31 mm case size sits at the larger end of the Lady-Datejust family and suits modern tastes that favor a more legible, presence-forward dial without crossing into full unisex territory. Reference 278381RBR pairs an Oystersteel case with Everose gold crown, lugs, and bracelet center links—what Rolex calls Rolesor—while the bezel is set with a continuous row of brilliant-cut diamonds, a hallmark of the RBR designation. This configuration is housed on the Jubilee bracelet, reinforcing its positioning as a jewel-quality statement watch that retains all of Rolex's signature durability and precision.
What to Look For
Within the 278381RBR family, dial choice is the primary differentiator and a key driver of secondary-market value; rarer colorways such as aubergine and slate command stronger collector interest than the more readily available silver or white mother-of-pearl options. Dial variants designated with V or J suffixes in the reference extension indicate diamond-set indexes rather than applied hour markers, adding another layer of brilliance and typically a higher retail and resale price point. Buyers should confirm the full reference code, dial color, and index type against original paperwork and box, as these details determine both authenticity and precise market valuation.
Frequently Asked Questions
What does the 278381RBR reference code mean?
The 278381 is the base model number for the Lady-Datejust 31, and RBR indicates an Oystersteel and Everose gold Rolesor case paired with a diamond-set bezel. Different suffix characters that follow the base code identify the specific dial color and index configuration, so two watches sharing the 278381RBR prefix may differ meaningfully in appearance and value.
What dial options are available for the Rolex Lady-Datejust 278381RBR?
Bizak and Co. stocks this reference in silver, chocolate, aubergine, slate, and white mother-of-pearl dials, with some variants featuring diamond-set indexes in addition to the diamond bezel. Each colorway gives the watch a distinct character, from the warm elegance of chocolate to the cooler, more dramatic look of slate or aubergine.
Is the Rolex Lady-Datejust 278381RBR a good investment?
The Lady-Datejust 31 in two-tone Rolesor with a diamond bezel has historically held its value well due to Rolex's enduring brand strength, the precious-metal content of the Everose gold components, and the sustained demand for dressed-up Datejust references. Rarer dial colors and diamond-index variants tend to perform especially well on the secondary market, making condition, completeness of box and papers, and dial specification the most important factors to evaluate before purchase.
