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

Reference 278384RBR belongs to the current generation of the Datejust 31, updated in 2021 and now powered by modern architecture throughout. In White Rolesor — Oystersteel paired with 18-carat white gold — it wears a factory diamond bezel and a pink diamond dial, a chromatic pairing that projects femininity without sacrificing the structural authority that defines the Oyster case family. The combination is one of Rolex's most commercially successful mid-size gem configurations.

Calibre 2236 drives this reference, the same movement found across the current Datejust 31 range. Its distinguishing technical feature is the Syloxi hairspring, machined from silicon in-house at Rolex and offering greater anti-magnetic performance than traditional alloys. The 55-hour power reserve, bidirectional Perpetual rotor winding, and COSC Superlative Chronometer certification place it firmly in the top tier of its class. The Oyster bracelet is rendered in matching White Rolesor.

On the secondary market, 278384RBR commands attention from collectors who understand that factory gem-set references depreciate more slowly than plain dial equivalents when in excellent condition with documentation. The RBR suffix — denoting a diamond-set bezel — is factory-original and cannot be replicated by aftermarket work without significantly diminishing value. This is a piece that rewards careful ownership.
