Datejust 31 Stainless Steel Fluted / Jubilee / MOP

About This Watch

The Rolex Datejust 31, with its refined silhouette and enduring design language, embodies the quiet confidence of a timepiece that has defined luxury watchmaking for generations. This particular iteration, distinguished by its fluted white gold bezel and a dial of luminous white mother-of-pearl, marries the collection’s heritage of elegant restraint with contemporary sophistication. The bezel’s subtle, concentric grooves echo the Datejust’s mid-20th-century origins, while the dial’s natural iridescence—captured in a material revered for its timeless beauty—adds a layer of quiet opulence. The stick-style hour markers and hands, paired with a gloss finish, ensure legibility without intruding on the watch’s harmonious balance, a hallmark of the collection since its 1945 debut. Encased in stainless steel and framed by a 31-millimeter diameter, the watch strikes a modern equilibrium between tradition and wearability, its proportions as deliberate as its craftsmanship. At its core lies the Caliber 2236, a self-winding movement that underscores Rolex’s mastery of precision engineering. With a power reserve of approximately 55 hours and a date display that aligns seamlessly

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.

278274-0006 is one of 34 executions of the 278274 base reference. Underneath they are the same watch; what separates this one is a white gloss dial. Introduced in 2020.

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.

906 other watches in the library run the Rolex 2236.
