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

About This Watch

The Rolex Datejust 31 Reference 278381RBR-0031 stands apart for its refined interplay of materials and timeless design, embodying the enduring legacy of the Datejust collection, which has defined elegant horology since its introduction in 1945. The dial, a luminous silver expanse, eschews traditional indexes in favor of a minimalist aesthetic, with slender stick hands that trace their path with quiet precision. A subtle floral motif, etched with meticulous craftsmanship, adds a touch of sophistication without overpowering the dial’s clean geometry. The case, a harmonious blend of rose gold and stainless steel, reflects Rolex’s mastery of metallurgy, while a diamond-set bezel elevates the piece to a level of understated opulence. The Oyster case, with its 100-meter water resistance, ensures durability without compromising the watch’s svelte 31-millimeter profile, a size that balances presence with discretion. At its heart lies the Caliber 2236, an in-house automatic movement renowned for its reliability and the seamless integration of the date function, a hallmark of Rolex’s engineering precision. The movement’s smooth operation and robust construction underscore the brand’s commitment to excellence, a principle that has guided Rolex for over a century. This watch is for the discerning individual who seeks a timepiece that transcends trends, serving as

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-0031 is one of 22 executions of the 278381RBR base reference. Underneath they are the same watch; what separates this one is a silver 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.
