Datejust 31 Stainless Steel / Yellow Gold / Fluted / Black MOP / Jubilee

About This Watch

The 278273-0024 Datejust 31 exemplifies Rolex’s mastery of blending timeless design with meticulous craftsmanship, offering a refined interpretation of the brand’s enduring legacy. This reference marries stainless steel and yellow gold in a harmonious balance, with a fluted bezel that echoes the iconic aesthetic of the Datejust collection, first introduced in 1945 as a symbol of elegant precision. The dial, a deep black mother-of-pearl surface with a gloss finish, is adorned with gem-set indexes that catch light with quiet sophistication, while stick hands provide a clean, legible contrast. The Jubilee bracelet, with its five-link design, adds a touch of understated opulence, ensuring comfort without compromising on luxury. At its core, the watch houses the Caliber 2236, a self-winding movement celebrated for its reliability and precision, featuring a Parachrom blue balance spring that enhances resistance to shocks and magnetic fields. The sapphire crystal, paired with a closed case back, underscores Rolex’s commitment to durability and discretion. This timepiece is not merely an object of desire but a testament to the brand’s philosophy of combining heritage with innovation. It is suited for those who seek a watch that transcends trends, serving as a versatile companion to both formal occasions and moments of quiet distinction,

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.

278273-0024 is one of 24 executions of the 278273 base reference. Underneath they are the same watch; what separates this one is a black gloss dial.

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.
