Datejust 31 Stainless Steel / Yellow Gold / Domed / Grey - Diamond / Jubilee

About This Watch

The Rolex Datejust 31 Reference 278243-0022 marries the brand’s enduring craftsmanship with a refined, contemporary silhouette. Its 31mm case, a blend of stainless steel and yellow gold, reflects a deliberate balance between tradition and modernity, while the domed crystal and rounded case profile evoke the timeless elegance of the Datejust collection, first introduced in 1945. The grey sunburst dial, a masterclass in subtlety, is framed by gem-set indexes that catch light with quiet sophistication, their placement echoing the precision of Rolex’s horological legacy. Stick hands, sharp and unadorned, complement the dial’s restraint, ensuring legibility remains paramount even in the most understated moments. The Jubilee bracelet, with its five-link design, adds a layer of comfort and sophistication, securing the watch to the wrist with a harmony of form and function. At its heart lies the Caliber 2236, an automatic movement celebrated for its reliability and the inclusion of a date display at the 3 o’clock position—a hallmark of the Datejust’s identity. The caseback, closed and unobtrusive, underscores the watch’s focus on wearability rather than ostentation. This piece is for the discerning individual who values heritage without sacrificing modernity, a collector who appreciates the quiet confidence of a watch that demands no explanation. It suits occasions where presence matters—boardrooms, soirées, or simply the quiet moments of daily life—worn as a testament to enduring taste and the quiet power of

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.

278243-0022 is one of 24 executions of the 278243 base reference. Underneath they are the same watch; what separates this one is a grey sunburst dial and a yellow 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.
