Rolex Datejust 31 White Rolesor — Pink Index Dial, 24-Diamond Domed Bezel | Ref. 278344RBR

Reference 278344RBR brings together White Rolesor construction — Oystersteel and 18ct white gold — with a domed bezel set with 24 brilliant-cut diamonds and a pink dial with index hour markers. The 278xxx prefix identifies this as a current-generation Datejust 31 reference, succeeding the earlier 178xxx series with updated case geometry and the newer Calibre 2236 movement. The pink dial adds a chromatic warmth that contrasts pleasingly with the cool white gold and diamond bezel setting, creating a watch with a distinct character well suited to both everyday and occasion wear in the 31mm segment.

Calibre 2236 powers this reference — Rolex's self-winding movement designed for 31mm and 28mm Datejust and Lady-Datejust models. A standout feature of the 2236 is its silicon Syloxi hairspring, which offers superior resistance to magnetic fields and temperature fluctuations compared to traditional alloy hairsprings. The Paraflex shock absorber adds impact resistance, and the movement delivers a power reserve of approximately 55 hours. The domed diamond bezel profile differs from the fluted and smooth options, providing additional visual texture. The Jubilee bracelet in Rolesor completes the warm-cool material pairing.

The 278344RBR is a considered choice within the Datejust 31 range for buyers who want a factory-jewelled watch with a gentle colour statement. Pink dials have seen increasing demand across the Rolex range in recent years, and this combination with a diamond domed bezel has proven particularly popular among buyers seeking a versatile dress piece. Rolex's factory stone-setting standards guarantee consistency that aftermarket alternatives cannot match, supporting the watch's long-term value proposition.
