Datejust 31 Stainless Steel/ Rose Gold / Diamond / Rose - Diamond / Oyster

About This Watch

The Rolex Datejust 31, in its 278381RBR-0023 iteration, marries the enduring elegance of the Datejust collection with a refined interplay of materials and craftsmanship. The case, a harmonious fusion of stainless steel and rose gold, frames a dial that exudes quiet sophistication—its sunburst rose finish catches light with subtle gradations, while the gem-set indexes add a discreet yet luxurious flourish. The stick hands, crisp and minimalist, complement the dial’s restrained opulence, ensuring legibility without sacrificing aesthetic restraint. As the flagship model of the Datejust line, which has defined timeless horology since its 1945 debut, this reference embodies the collection’s legacy of balancing innovation with tradition. At its core, the watch is powered by Rolex’s in-house automatic movement 2236, a testament to the brand’s mastery of precision engineering. The movement’s chronometer certification and robust construction underscore its reliability, while the 100-meter water resistance ensures practicality without compromising the watch’s svelte profile. The Oyster case, paired with a sapphire crystal, reinforces the Datejust 31’s reputation for durability and sophistication. This timepiece is for the discerning individual who values understated refinement and heritage. It suits occasions that demand both presence and subtlety—a gala, a boardroom meeting, or simply a quiet moment of appreciation. Its design speaks to those who seek a companion that transcends trends, marrying the enduring language of luxury with the quiet confidence of a watch that needs no introduction.

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.

278381RBR-0023 is one of 22 executions of the 278381RBR base reference. Underneath they are the same watch; what separates this one is a rose 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.
