Rolex Datejust 31 Ref. 278273-0021 — Oystersteel and Yellow Gold Fluted Bezel Oyster Watch

The Rolex Datejust 31 Ref. 278273-0021 is a Yellow Rolesor Datejust — 31mm Oystersteel case with an 18k yellow gold fluted bezel, dark grey dial, and Oyster bracelet. Case Shape: Round. Powered by Calibre 2236 with Syloxi silicon hairspring and 55-hour power reserve, certified Superlative Chronometer to -2/+2 seconds per day after casing.

Yellow Rolesor — The Enduring Two-Tone

The Yellow Rolesor configuration pairs Oystersteel with 18k yellow gold on the fluted bezel, crown, and Oyster bracelet centre links — a combination that has defined the Datejust aesthetic for decades. The fluted yellow gold bezel catches light from every angle, creating the signature Datejust look that remains as contemporary today as when Gerald Genta first drew it.

The Dark Grey Dial

The dark grey dial is produced at Rolex’s in-house dial manufacturing facilities, where each finish is developed to the exacting Superlative Chronometer standards the Datejust demands. Diamond-set hour markers add brilliance to the composition, each stone individually set by Rolex’s in-house gem-setters. The date display at 3 o’clock with Cyclops lens provides 2.5x magnification.
