About This Watch

Introduced at Baselworld 2019, reference 278383RBR marked Rolex's elevation of the Datejust 31 into a new generation of design — cleaner, more architecturally resolved, and powered by the remarkable Calibre 2236. The Yellow Rolesor construction — pairing 904L Oystersteel with 18K yellow gold — creates that instantly recognisable two-tone aesthetic that has proven consistently compelling across decades, here elevated further by a bezel pavé-set with brilliant-cut diamonds that glitter against the yellow gold crown and bracelet links.

The white dial with Roman numeral hour markers offers a classical legibility that feels deliberately considered. Roman numerals on a Datejust occupy a storied lineage stretching back to the reference 1600 era, and their revival on this Baselworld 2019 piece signals Rolex's confidence in horology's enduring aesthetic vocabulary. The Cyclops lens magnifies the date at 3 o'clock with characteristic precision, while the dial's clean white ground provides ideal contrast for both the numerals and the hands.

The Calibre 2236 inside is a movement of modern distinction: its silicon Syloxi hairspring renders it effectively non-magnetic, while the bidirectional Perpetual rotor ensures reliable winding through ordinary wrist motion. Approximately 55 hours of power reserve, instantaneous date, and stop-seconds complete the specification. Presented on the yellow Rolesor Oyster bracelet with Oysterclasp and Easylink comfort extension, reference 278383RBR is among the most complete expressions of the contemporary Datejust 31 — jewelled, classical, and technically exemplary in equal measure.
