Rolex Datejust 31 31 mm 278274WMOPDO Steel/White Gold White Mother of Pearl

The Rolex Datejust is the archetype of the classic dress watch, introduced in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock—a complication so influential that it defined an entire category. Across nearly eight decades the Datejust has remained in continuous production, evolving in case sizes, materials, and dial executions while retaining the instantly recognizable silhouette that makes it one of the most coveted watches in the world. The 31mm format has long been the preferred choice for those who appreciate a mid-sized, versatile case that wears elegantly on a wide range of wrists without sacrificing the bold identity of the Rolex crown.

Reference 278274WMOPDO represents one of the most refined expressions within the current Datejust 31 collection. The case is crafted in Rolex's proprietary Oystersteel—a 904L stainless steel alloy renowned for its exceptional corrosion resistance and mirror-bright polish—combined with 18k white gold on the bezel and crown, creating a two-tone harmony that reads as quietly luxurious rather than overtly showy. At 31mm in diameter, the Oyster case is perfectly proportioned: substantial enough to command attention, refined enough to slip beneath a cuff.

The dial is the centerpiece of this reference and the detail that elevates it above its steel siblings. White mother-of-pearl is a naturally occurring material harvested from mollusc shells, meaning every dial is uniquely patterned with its own soft iridescent shimmer—no two are exactly alike. Against this shifting canvas of ivory, cream, and pale silver, the applied Rolex hour markers and hands catch the light with quiet authority. The white gold fluted bezel—one of the most storied design signatures in watchmaking—adds a further layer of brilliance, its precisely machined ridges reflecting light at every angle and reinforcing the dress-watch pedigree of the piece.

Powering the watch is a Rolex automatic movement, housed within the hermetically sealed Oyster case that delivers 100 metres (330 feet) of water resistance. The Oyster bracelet—arguably the most copied bracelet design in watchmaking history—completes the package, linking the case to the wrist with a combination of polished center links and satin-finished outer links that echo the case's own finishing. The Easylink comfort extension system integrated into the clasp allows for fine adjustment, ensuring the bracelet fits perfectly in any condition.

For collectors and first-time Rolex buyers alike, the Datejust 31 ref. 278274WMOPDO occupies a compelling position: it is a certified authentic, brand-new example presented with full box and papers, offering complete peace of mind on provenance and condition. The mother-of-pearl and white gold specification is perennially desirable and holds its character over decades of wear, making this as sound an acquisition from an investment perspective as it is a joy to wear daily.
