Datejust 31 Rose Gold / Fluted / Chocolate - Diamond / President

About This Watch

The Rolex Datejust 31 in rose gold, with its fluted bezel and chocolate dial, embodies the quiet authority of a timepiece that has defined elegance for generations. Introduced in 1945, the Datejust collection established itself as a benchmark for sophistication, and this 31mm iteration—worn on the iconic President bracelet—retains the lineage of understated refinement. The dial’s sunburst brown finish, paired with gem-set indexes, creates a subtle interplay of light that shifts with the wearer’s movements, while the stick hands offer a minimalist counterpoint to the opulence of the rose gold case. The fluted bezel, a hallmark of Rolex’s design language, adds a tactile and visual dimension that has remained largely unchanged since the collection’s inception, underscoring its timeless appeal. At its core, the watch houses the Caliber 2236, an in-house automatic movement that marries precision engineering with the reliability expected of a luxury watch. Its 100-meter water resistance and the smooth, uninterrupted sweep of the date function—visible through the sapphire crystal—reflect the meticulous attention to detail that defines Rolex’s craft. The President bracelet, with its five-piece link construction, ensures both comfort and a secure fit, making it as practical as it is polished. This watch is for those who value discretion as much as craftsmanship, a companion for both formal occasions and the quiet moments of everyday life. It speaks in a language of subtlety, where heritage and modernity converge without fanfare.

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.

278275-0010 is one of 25 executions of the 278275 base reference. Underneath they are the same watch; what separates this one is a brown sunburst dial and a rose gold 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.
