The Rolex Datejust 31 reference 278273-0023 is a sophisticated mid-size timepiece that harmoniously blends the durability of Oystersteel with the luxury of 18k yellow gold in a signature Yellow Rolesor configuration. The 31mm case features a polished finish and is crowned with a solid 18k yellow gold fluted bezel, a hallmark of the Datejust collection. The standout feature is its black mother-of-pearl dial, a natural material that ensures every piece is unique, adorned with ten diamonds set in 18k gold settings. This model is paired with a three-piece link Oyster bracelet, which includes a folding Oysterclasp and the Easylink 5mm comfort extension system for easy adjustments.
At its core, the watch is powered by the manufacture Rolex Caliber 2236, a self-winding mechanical movement that utilizes a Syloxi silicon hairspring to remain unaffected by magnetic fields and temperature variations. This Superlative Chronometer certified movement provides a power reserve of approximately 55 hours and maintains a precision of -2/+2 seconds per day. The watch offers essential complications, including central hours, minutes, and seconds, along with an instantaneous date display at the 3 o’clock position magnified by a Cyclops lens. Its architecture includes a screw-down Twinlock winding crown and case back, ensuring water resistance up to 100 meters.
General reviews of the Datejust 31 series emphasize its versatility and ideal proportions, noting that the 31mm size provides a more significant wrist presence than the traditional 28mm Lady-Datejust while remaining elegant for formal occasions. The 278273 reference specifically is often praised for the striking contrast between its dark, iridescent mother-of-pearl dial and the warm tones of the yellow gold. Collectors and critics appreciate the technical reliability of the Caliber 2236, though some note that the high demand for specific dial configurations can make certain models difficult to acquire at retail. Overall, it is regarded as an enduring and practical luxury watch that bridges the gap between a jewelry piece and a professional-grade instrument.
