Datejust 31 Rose Gold / Domed / Chocolate - Diamond / Oyster

About This Watch

The Rolex Datejust 31, in its rose gold iteration with a chocolate dial, embodies the enduring elegance of a collection that has defined luxury watchmaking for generations. This particular reference, distinguished by its domed sapphire crystal and gem-set indexes, marries classic design with refined modernity. The sunburst brown dial, framed by a rose gold bezel, exudes warmth and depth, while the stick hands and subtly placed diamond add a quiet sophistication that avoids ostentation. The Datejust’s heritage as a symbol of timeless sophistication is evident in every detail, from its enduring round case to the meticulous craftsmanship of its Oyster construction, ensuring both resilience and aesthetic harmony. At its heart lies the Caliber 2236, a self-winding movement renowned for its precision and reliability, a testament to Rolex’s mastery of in-house engineering. The 31mm case, balanced between presence and subtlety, is complemented by a water resistance of 100 meters, a practicality that does not compromise the watch’s role as a statement of quiet distinction. This piece is for the discerning

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.

278245-0015 is one of 24 executions of the 278245 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.
