Datejust 31 Stainless Steel/ Rose Gold / Domed - Diamond / Chocolate - Diamond / Jubilee

About This Watch

The Rolex Datejust 31, in its 278341RBR-0028 iteration, embodies a refined balance of tradition and modernity, distinguished by its harmonious union of stainless steel and rose gold. The dial, a rich chocolate brown with a sunburst finish, exudes quiet sophistication, its depth enhanced by the subtle interplay of gem-set indexes that catch light with understated elegance. The stick hands, paired with a domed sapphire crystal, frame the dial with clarity and precision, while the Jubilee bracelet—characteristic of the Datejust lineage—offers a comfortable, polished fit that transitions seamlessly from formal to casual settings. As the flagship model of a collection first introduced in 1945, the Datejust 31 continues to represent Rolex’s commitment to timeless design, its 31mm case size reflecting a contemporary sensibility without sacrificing the brand’s storied heritage. Beneath the caseback lies the Caliber 2236, an automatic movement renowned for its reliability and smooth operation, ensuring the watch’s functionality aligns with its aesthetic refinement. The water resistance of 100 meters further underscores its practicality, though it remains a piece more suited to moments of quiet distinction than rugged utility. This watch is for the discerning individual who values subtlety over ostentation, seeking a timepiece that speaks to legacy and craftsmanship without demanding attention. It is the companion for evening engagements, boardroom meetings, or quiet mornings, its presence a testament to the wearer’s appreciation for enduring quality and 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.

278341RBR-0028 is one of 24 executions of the 278341RBR base reference. Underneath they are the same watch; what separates this one is a brown 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.
