About This Watch

The Rolex Datejust 31 in stainless steel and rose gold embodies a refined balance of tradition and modernity, distinguished by its domed case and the subtle interplay of materials that define its character. The grey sunburst dial, with its radial finish and understated stick indexes, evokes the timeless elegance of early Datejust models while benefiting from contemporary refinements. The rose gold bezel and stainless steel case merge seamlessly, a nod to the collection’s long-standing legacy of combining durability with sophistication. The Jubilee bracelet, with its gentle curvature and polished links, enhances the watch’s wearability without compromising its formal demeanor. As the flagship model of the Datejust collection, which debuted in 1945 as the first self-winding waterproof chronometer-certified watch, this reference honors a heritage of precision and innovation. The Caliber 2236 movement, developed in-house by Rolex, ensures exceptional reliability with a power reserve of approximately 55 hours, its construction reflecting the brand’s commitment to mechanical excellence. The domed sapphire crystal, paired with a closed case back, further underscores the watch’s robustness and attention to detail. This timepiece is suited for those who value discretion as much as craftsmanship—whether for a quiet evening in

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.

278241-0018 is one of 24 executions of the 278241 base reference. Underneath they are the same watch; what separates this one is a grey 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.

906 other watches in the library run the Rolex 2236.
