Rolex Datejust 31 Yellow Gold — Paved Mother-of-Pearl Butterfly Dial | Ref. 278288RBR

Reference 278288RBR is among the most jewel-intensive configurations available in the Datejust 31 collection. The yellow gold case is set with a diamond bezel in the RBR designation, and the dial takes the precious material theme further with a paved mother-of-pearl surface arranged in a butterfly motif — a design that places Rolex firmly in high-jewellery territory while retaining the technical foundations of a proper mechanical timepiece. This is not simply an aesthetic exercise; the craftsmanship required to produce and set these dials is considerable.

Calibre 2236 powers this reference, developed specifically for Rolex's 31 mm range. It features the Syloxi silicon hairspring, COSC-certified accuracy, and a 55-hour power reserve — a movement that takes the complications of the precious metal case seriously. The 18ct yellow gold case and bracelet are finished with the same care applied to Rolex's more austere models, with the added complexity of the set diamond bezel demanding precise alignment and secure stone setting throughout the piece.

Buyers considering this reference are generally shopping at the intersection of fine jewellery and watchmaking. The butterfly dial is a limited and sought-after decoration, and yellow gold with diamond RBR bezel commands significant premiums over base Datejust 31 configurations. On the secondary market, demand is driven by those purchasing as much for gift-giving and special occasions as for daily wear. Condition of the diamond setting and the original bracelet is paramount — replaced bracelets or re-polished bezels will affect value materially. Full set with box and papers is essentially expected at this price level.
