Datejust 31 Stainless Steel/ Rose Gold / Domed - Diamond / Aubergine - Roman / Jubilee

About This Watch

The Rolex Datejust 31, in its 278341RBR-0020 iteration, marries the brand’s enduring legacy of precision with a refined interplay of materials and color. The case, a harmonious blend of stainless steel and rose gold, frames a dial that evokes the deep, velvety hue of aubergine, its sunburst finish catching light with subtle, radial depth. Roman numerals, rendered in a contrasting tone, anchor the dial’s elegance, while stick hands trace their path with quiet authority. The domed sapphire crystal, a hallmark of Rolex’s craftsmanship, enhances the dial’s presence without intruding on its understated sophistication. This reference, part of the Datejust collection—a lineage established in 1945 as a symbol of timeless elegance—retains the collection’s signature balance between classicism and innovation. Beneath the caseback lies the Caliber 2236, an automatic movement with a date display, its reliability and precision a testament to Rolex’s mastery of mechanical engineering. The Jubilee bracelet, with its five-link design, complements the watch’s duality of sport and sophistication, ensuring comfort without compromising on the brand’s iconic aesthetic. This timepiece is for those who value discretion as much as heritage, a companion for moments that demand quiet confidence—whether in the boardroom, at a gala, or on the wrist of someone who understands that true luxury lies in the marriage of form and function.

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.

278341RBR-0020 is one of 24 executions of the 278341RBR base reference. Underneath they are the same watch; what separates this one is a purple 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.
