Rolex Datejust 31 31 mm 278274SSO Steel/White Gold Silver

The Rolex Datejust is arguably the most iconic dress watch ever made, having introduced the instantaneously jumping date display to wristwatches when it debuted in 1945. Over nearly eight decades the design has remained immediately recognizable while evolving in proportion, material, and finishing — a testament to Rolex's commitment to refinement without reinvention. The 31mm case size sits at the heart of the modern Datejust family, sized to sit elegantly on a wide range of wrists without sacrificing legibility or presence.

Reference 278274SSO occupies a particularly prestigious position within the current Datejust 31 collection by combining two materials that bring out the best in each other. The case and bracelet are fashioned from Oystersteel, Rolex's proprietary 904L stainless steel alloy celebrated for its exceptional corrosion resistance and mirror-bright polish, while the bezel and crown-side case elements are crafted in 18k white gold. This combination — known in Rolex parlance as a two-tone or Rolesor configuration — delivers a look that is simultaneously sporty and luxurious.

The silver dial of the 278274SSO is a study in restrained elegance. Silver dials in the Datejust family typically feature applied hour markers with luminescent fills and matching hands, ensuring outstanding legibility in all lighting conditions. The date aperture at 3 o'clock, framed by a Cyclops lens on the crystal for 2.5× magnification, is the defining complication that gives the Datejust its name and purpose. The overall effect is clean, authoritative, and timeless.

The white gold fluted bezel is one of the Datejust's most storied design signatures. Originally conceived as a practical milling technique to help tighten the bezel onto the case, the fluted motif evolved into a pure design icon that catches light at every angle. On the 278274SSO the bezel is solid 18k white gold, its crisp ridges contrasting beautifully with the polished and brushed surfaces of the Oystersteel case and Oyster bracelet below. Rolex rates the Oyster case to 100 meters (330 feet) of water resistance, delivered by the twinlock winding crown and sapphire crystal.

Powering the watch is an automatic movement produced entirely in-house by Rolex, consistent with the brand's longstanding practice of manufacturing its own calibers to chronometer-certified precision standards. The self-winding rotor winds the mainspring bidirectionally, making the watch ideally suited to everyday wear — it stays wound simply by the natural motion of the wrist. Rolex's movements are renowned for long-term reliability and serviceability, reinforcing the Datejust's reputation as a watch that can be worn and enjoyed across generations.
