About the Rolex Datejust 31 278344RBR
The Datejust is Rolex's longest-running and most recognizable collection, introduced in 1945 as the first self-winding wristwatch to display the date in a magnified aperture at 3 o'clock—a feature Rolex calls the Cyclops lens. The 31 mm case size has become a cornerstone of the modern Datejust lineup, offering a proportional middle ground that the brand markets to both women and men seeking a refined yet wearable silhouette. Reference 278344RBR is distinguished specifically by its Rolesor pairing of Oystersteel and 18k white gold alongside a factory-set diamond bezel, elevating it firmly into luxury-jewellery-watch territory while retaining the tool-watch DNA—screw-down crown, Oyster bracelet, and certified chronometer movement—that defines every Rolex. The suffix letters following the base reference number denote dial configuration, allowing collectors to target exact combinations such as the green sunray dial 278344RBRGNSO or the pink dial 278344RBRPRO without ambiguity.
What to Look For
When shopping the 278344RBR collection, the primary differentiator is dial color and finish: options range from the high-contrast 278344RBRBKRO and 278344RBRBKRJ black dials to the bright 278344RBRWRO white and the on-trend 278344RBRGNSO green, with grey and silver sunray variants rounding out the lineup for buyers who prefer understated elegance. Value within this reference group is influenced by dial rarity and current market demand—green and pink dials have attracted strong collector interest in recent years—as well as overall condition, presence of original box and papers, and whether the example is unworn or lightly pre-owned.
