Datejust 31 Stainless Steel/ Rose Gold / Domed / Chocolate - Diamond / Jubilee

About This Watch

The Rolex Datejust 31 Reference 278241-0028 embodies a refined synthesis of tradition and modernity, distinguished by its harmonious pairing of stainless steel and 18ct rose gold. The case’s domed sapphire crystal, a hallmark of Rolex’s engineering precision, frames a dial that exudes quiet sophistication—a rich, sunburst-finished brown hue that deepens with light. The gem-set indexes, meticulously arranged, add a subtle sparkle without overshadowing the dial’s timeless elegance, while the stick hands provide a clean, legible contrast. As the flagship model of the Datejust collection, which first introduced the date display on the dial in 1945, this reference honors a legacy of innovation and enduring design, reimagined for contemporary wear. At its core lies the Caliber 2236, a self-winding movement with a 55-hour power reserve, engineered to deliver the accuracy and reliability synonymous with Rolex. The watch’s 100-meter water resistance and 16mm lug width ensure both practicality and a balanced silhouette, complemented by the Jubilee bracelet’s signature comfort and refinement. This piece is suited for those who seek a timepiece that transcends trends, offering a quiet assertion of status through its understated luxury. It is the kind of watch that thrives in the quiet moments—whether at a formal dinner, a private meeting

In Context

At 31 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 55 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

278241-0028 is one of 24 executions of the 278241 base reference. Underneath they are the same watch; what separates this one is a brown sunburst dial and a rose gold, stainless steel case.

The 2236 is the Rolex movement inside more watches in this library than any other: 907, in the 28 mm Lady-Datejust and the 31 mm Datejust 31. It was the first Rolex caliber with a silicon hairspring. Introduced in 2014 in the Pearlmaster 34, it is a 20 mm automatic with a date, 31 jewels, a 55-hour reserve and a beat of 28,800 vph, certified by the COSC and then tested again by Rolex after casing to the Superlative Chronometer tolerance of two seconds a day. Its distinction is the Syloxi hairspring: silicon, immune to magnetism, etched to a patented geometry that keeps the spring concentric in every position, and paired with Paraflex shock absorbers. The larger Rolex calibers kept the Parachrom alloy spring; Syloxi did not reach a men's movement until the 7140 of 2023. The [2236 piece](/blog/the-rolex-2236-the-most-common-movement-in-this-library) sets out that history. In the library it powers 488 [Datejust 31](/brands/rolex/datejust-31) references, the seven-digit 2782xx generation of 2020, 399 [Lady-Datejusts](/brands/rolex/lady-datejust) of the 2791xx generation of 2015, 15 [Pearlmasters](/brands/rolex/pearlmaster) and 5 [Yacht-Master 37s](/brands/rolex/yacht-master). The [2235](/calibers/rolex-2235) is the 48-hour movement it replaced, the [2232](/calibers/rolex-2232) its no-date sibling for the Oyster Perpetual, and the [3235](/calibers/rolex-3235) its counterpart in the 36 mm and 41 mm cases.
