Rolex Datejust 31 White Rolesor — Diamond Bezel Pink Index Dial | Ref. 278384RBR

The 278384RBR is among the more decoratively intensive references in the current 31mm Datejust catalogue, combining a diamond-set bezel with a pink index dial on a White Rolesor platform. White Rolesor pairs 18-carat white gold for the bezel and crown with an Oystersteel case body — the cooler tonal balance of white gold against steel produces a more contemporary feel than either yellow or Everose Rolesor combinations. The diamond bezel replaces the traditional fluted or smooth options with a fully pavé-set ring, elevating this reference firmly into jewellery-watch territory.

Calibre 2236 is the movement of choice for current-production 31mm Datejust references. It features Rolex's proprietary Syloxi silicon hairspring, which provides enhanced anti-magnetic performance and contributes to the COSC chronometer certification. The pink index dial provides a warm counterpoint to the white gold and diamond exterior, the applied hour markers catching light independently of the bezel stones. The 31mm Oyster case is water-resistant to 100 metres and finished with a combination of polished and brushed surfaces that highlight the case's geometric lines.

This reference targets buyers who want substantial diamond presence without moving to the full Day-Date or Pearlmaster format. The 278xxx numbering confirms current-generation production, meaning Calibre 2236, updated case finishing, and the improved Rolex guarantee terms now offered with new watches. On the secondary market, diamond-bezel Datejust 31 references command a meaningful premium over smooth or fluted-bezel counterparts, and condition of the pavé setting — checking for missing or chipped stones — is the primary inspection priority for any prospective buyer.
