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

About This Watch

The Rolex Datejust 31, in its 278341RBR-0002 iteration, exemplifies the quiet sophistication of a timepiece that balances tradition with contemporary refinement. This particular reference marries the enduring elegance of the Datejust collection—introduced in 1945 as a symbol of precision and accessibility—with a striking interplay of materials. The case, a harmonious blend of stainless steel and rose gold, frames a white dial finished to a high gloss, its Roman numeral indexes and slender stick hands evoking a timeless aesthetic. The domed sapphire crystal, paired with a closed case back, enhances the watch’s robust yet refined silhouette, while the Jubilee bracelet, with its gently curved links, ensures a comfortable fit that transitions seamlessly from formal wear to casual settings. At its core, the watch houses the Caliber 2236, an automatic movement derived from Rolex’s legendary Caliber 2200, offering a 48-hour power reserve and a date function that operates with the brand’s signature precision. The 31mm case diameter, paired with a 16mm lug width, ensures a proportionate presence on the wrist, a testament to Rolex’s commitment to wearable luxury. This reference, though not overtly ostentatious, carries the weight of the Datejust’s legacy—a collection that has long defined the intersection of craftsmanship and everyday elegance. Suited for the discerning individual who values understated sophistication, this watch is an ideal companion for those who seek a timepiece that transcends trends, marrying heritage with the subtle luxury of a well-crafted, enduring design.

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-0002 is one of 24 executions of the 278341RBR base reference. Underneath they are the same watch; what separates this one is a white gloss 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.
