Datejust 31 Rolesor Yellow Fluted Diamond / Jubilee / Silver Diamond

About This Watch

The Rolex Datejust 31, in its Rolesor iteration of yellow gold and stainless steel, embodies a quiet mastery of balance—between tradition and innovation, form and function. This specific model, distinguished by its fluted bezel and diamond-set Jubilee bracelet, channels the enduring elegance of the Datejust collection, first introduced in 1945 as a symbol of accessible luxury. The silver dial, finished with a sunburst pattern, reflects light with subtle sophistication, its stick indexes and hands framed by a bezel that echoes the iconic fluting first seen on the Oyster Perpetual in the 1940s. The diamond-set lugs and bracelet add a touch of refinement without overt ostentation, underscoring the Datejust’s reputation as a watch that transcends trends. At its heart lies the Caliber 2235, a self-winding movement with a certified chronometer rating, ensuring precision and reliability. Its date mechanism, seamlessly integrated into the dial, exemplifies Rolex’s commitment to technical excellence. The case, crafted from yellow gold and stainless steel, is both resilient and timeless, its 31mm diameter offering a modern proportion while honoring the Datejust’s legacy as a versatile, everyday luxury watch. This timepiece is for the discerning individual who values heritage, craftsmanship, and understated distinction. It is a companion for moments that demand quiet confidence—whether in boardrooms, at cultural events, or during journeys that span continents. Its presence is not declared, but felt.

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. 48 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.

178313-0027 is one of 31 executions of the 178313 base reference. Underneath they are the same watch; what separates this one is a silver sunburst dial and a yellow gold, stainless steel case.

The 2235 is the small Rolex automatic of the six-digit generation, a 20 mm movement with a date. It carried the Datejust 31 and the 26 mm Lady-Datejust from around 2000 until the 2236 replaced it. It powers 733 watches in this library. It has 31 jewels, a 48-hour reserve and a beat of 28,800 vph, and every one is a COSC chronometer. It is the same architecture as the [2236](/calibers/rolex-2236) that followed, without the silicon Syloxi hairspring and with seven hours less reserve; the [2236 piece](/blog/the-rolex-2236-the-most-common-movement-in-this-library) explains what changed. The library finds it almost entirely in the [Datejust 31](/brands/rolex/datejust-31): 682 references, the 1782xx generation, whose 45 base references and hundreds of dial variants make that collection the largest here. The 26 mm [Lady-Datejust](/brands/rolex/lady-datejust) of the 1791xx generation accounts for 29, the [Pearlmaster](/brands/rolex/pearlmaster) 29 mm and 34 mm for 19, and the 35 mm Yacht-Master for 3. A six-digit Datejust 31 reference is a 2235; the seven-digit one is a 2236, as the [reference-number guide](/blog/how-to-read-a-watch-reference-number) explains. The 2231 was its no-date sibling in the Oyster Perpetual, and the [3135](/calibers/rolex-3135) its counterpart in the 36 mm cases.

732 other watches in the library run the Rolex 2235.
