About the Rolex Datejust 31 278289RBR
The Rolex Datejust is one of the most enduring watch designs in horological history, introduced in 1945 as the first self-winding wristwatch to display the date through a magnifying Cyclops lens on the crystal. The 31 mm case size has long served as Rolex's midsize offering, proportioned between the ladies 28 mm and the full-size 36 mm, making it a versatile choice for a wide range of wrists. Reference 278289RBR specifies the white gold Oyster case paired with a factory diamond-set bezel, a combination that places this watch firmly in Rolex's precious-metal tier. The varied dial palette — spanning warm pinks and aubergine to cooler silver, grey, green, and dramatic black — allows collectors to express distinct personal aesthetics within a single, coherent reference.
What to Look For
When shopping the 278289RBR family, dial color and specific dial finish are the primary differentiators: suffix codes such as PRVIDP indicate a pink diamond-set dial, BKRP denotes a black Roman numeral dial, GNSP points to a green sunray, and ARVIDP signals the rare aubergine diamond dial, each commanding different premiums in the secondary market. Condition of the diamond bezel and bracelet, presence of original box and papers, and whether the watch retains its factory service history are the key value drivers to evaluate before you buy.
Frequently Asked Questions
What does the 278289RBR reference number mean?
In Rolex nomenclature, 278289 designates the 31 mm Datejust in 18k white gold with an Oyster case, while the RBR suffix confirms that the bezel is set with a row of brilliant-cut diamonds from the factory. The additional letter codes after RBR in each product listing identify the specific dial color, material, and hour-marker style.
Is the Rolex Datejust 31 278289RBR a good investment?
White gold diamond-bezel Datejust references in the 31 mm size have historically held strong value on the secondary market because precious-metal Rolex sports and dress watches benefit from both brand prestige and the intrinsic value of the materials. Rare dial colors such as aubergine or green tend to attract collector premiums above more common options like silver or pink. Retaining original box, papers, and service documentation further supports resale value.
How does the 278289RBR differ from the 278274 or 278274RBR?
The 278289RBR is distinguished by its full 18k white gold Oyster case and bracelet combined with a factory diamond bezel, placing it above references that use a steel or Rolesor case construction. The 278274RBR, by contrast, pairs a white Rolesor — steel case with white gold bezel — construction with a diamond bezel, making it a more accessible entry point. Buyers seeking an all-white-gold statement piece will want to confirm the 278289 case reference before purchasing.
