Datejust 31 Rolesor Yellow Fluted Diamond / Jubilee / MOP

About This Watch

The Rolex Datejust 31, in its Rolesor Yellow Fluted Diamond iteration, embodies a quiet mastery of balance between tradition and refinement. The 31mm case, crafted from 18ct yellow gold and stainless steel, features the signature fluted bezel—a design element first introduced in 1945 that has since become synonymous with the Datejust collection’s enduring elegance. The dial, a luminous white mother-of-pearl, is framed by gem-set indexes that catch light with subtle precision, while the stick hands add a timeless, minimalist counterpoint to the opulence of the setting. The Jubilee bracelet, with its five-link design and polished finish, complements the case’s dual-material construction, offering both comfort and a sense of quiet authority. At the heart of the watch lies the Caliber 2235, a self-winding movement with a 70-hour power reserve, certified for chronometric precision by the COSC. This technical rigor is paired with the Datejust 31’s sapphire crystal and water resistance to 100 meters, ensuring durability without compromising the watch’s delicate aesthetic. The collection’s heritage—as the first luxury watch to feature a date display on the dial—lends the piece a quiet gravitas, a testament to Rolex’s role in redefining horological standards. This watch is for those who value understated sophistication, whose presence is marked by restraint rather than ostentation. It suits formal occasions with the same ease it brings to everyday moments of significance, a companion for the discerning who seek a timepiece as enduring as their own legacy.

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.

178313-0035 is one of 31 executions of the 178313 base reference. Underneath they are the same watch; what separates this one is a white dial.

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.
