Datejust 31 Rose Gold / Domed / Chocolate - Diamond / President

About This Watch

The Rolex Datejust 31, in its 278245-0016 iteration, embodies the quiet authority of a timepiece that balances tradition with refined modernity. Rose gold, a material synonymous with Rolex’s mastery of precious metals, forms the case, its warm hue complemented by a domed sapphire crystal that enhances the watch’s presence without drawing undue attention. The dial, a rich brown with a sunburst finish, exudes understated elegance, its gem-set indexes adding a subtle sparkle that catches light only when desired. Stick hands, precise and unadorned, trace the passage of time with a clarity that reflects the Datejust collection’s enduring legacy since its introduction in 1945. This collection, a cornerstone of Rolex’s identity, has long represented the intersection of craftsmanship and accessibility, and the 31mm diameter ensures its proportions remain discreetly imposing. At the heart of the watch lies the Caliber 2236, an automatic movement distinguished by its date display and a power reserve of approximately 50 hours, a testament to Rolex’s commitment to precision and reliability. The closed case back, paired with the Oyster case’s water resistance to 100 meters, underscores the brand’s engineering ethos—where durability and sophistication coexist. The President bracelet, with its three-piece links and polished finish, completes the ensemble, offering a level of comfort and refinement that aligns with the watch’s purpose. This timepiece is for the individual who values heritage without ostentation, whose discernment lies in the subtleties of design and the quiet confidence of a watch that needs

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.

278245-0016 is one of 24 executions of the 278245 base reference. Underneath they are the same watch; what separates this one is a brown sunburst dial and a rose gold 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.
