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

About This Watch

The Rolex Datejust 31 reference 278341RBR-0023 embodies a refined interplay of materials and craftsmanship, blending the enduring elegance of stainless steel with the warmth of rose gold. At 31mm in diameter, its case is a study in balance, with a domed sapphire crystal that enhances the watch’s presence while ensuring clarity and durability. The dial, a deep rose hue with a sunburst finish, is framed by gem-set indexes that catch light with quiet sophistication, their placement echoing the Datejust collection’s legacy of precision and timeless design since its introduction in 1945. Stick hands, sleek and legible, complement the dial’s understated grandeur, while the closed caseback invites contemplation of the mechanical artistry within. At its heart lies the Caliber 2236, an automatic movement certified as a chronometer for its accuracy and reliability. This movement, with its Parachrom balance spring and 38-hour power reserve, underscores Rolex’s commitment to engineering excellence, ensuring the watch performs with unwavering consistency across conditions. The 100-meter water resistance and Oyster case construction further reinforce its resilience, a hallmark of the brand’s heritage. This watch is for those who value heritage as much as horology, seeking a piece that transcends trends yet remains instantly recognizable. It suits moments of quiet distinction—whether marking a personal milestone or complementing a formal occasion—worn with the confidence of a collector who understands that true luxury lies in the harmony of form, function, and legacy.

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-0023 is one of 24 executions of the 278341RBR 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.
