Description
The Rolex Datejust traces to 1945 as the first self-winding waterproof chronometer to display the date through an aperture — among the most foundational references in watchmaking history. The Datejust 31 represents the model’s mid-size execution, refined into a proportion that has become a signature within Rolex’s catalog. Reference 278273 is the contemporary two-tone Rolesor configuration, combining stainless steel with 18-karat yellow gold and presented here in one of the more distinctive dial appointments Rolex offers: natural black mother-of-pearl with factory diamond hour markers. The dark mother-of-pearl captures shifting iridescent tones — blue, green, and purple — that change with the light, ensuring every example displays a unique character.
The 31mm Oyster case in stainless steel features an 18-karat yellow gold fluted bezel and Twinlock screw-down crown. The black mother-of-pearl dial carries diamond hour markers in 18-karat yellow gold settings, yellow gold hands with luminescent fill, and a date aperture at three beneath the Cyclops magnifier. The in-house automatic Caliber 2236 — equipped with Rolex’s patented Syloxi silicon hairspring and Paraflex shock absorbers — delivers a 55-hour power reserve and Superlative Chronometer certification, completed by a two-tone Jubilee bracelet with five-piece links and folding Crownclasp.
*This timepiece comes with the original white hang tag.
