Datejust 31 Rolesor Yellow Domed / Jubilee / White Roman

About This Watch

The Rolex Datejust 31 in Rolesor—a harmonious union of yellow gold and stainless steel—embodies the enduring elegance of the Datejust collection, first introduced in 1945 as a symbol of refined precision. This particular iteration, with its domed white dial and subtle Roman numeral indexes, marries classic horological restraint with modern sophistication. The stick hands, rendered in a crisp, minimalist form, complement the dial’s clean architecture, while the sapphire crystal ensures clarity and durability. The 31mm case, balanced between presence and discretion, is framed by a Jubilee bracelet, whose five-link design has long been synonymous with Rolex’s commitment to both comfort and timeless aesthetics. At its core, the watch houses the Caliber 2235, a self-winding movement distinguished by its date display and a power reserve of approximately 50 hours. This mechanical heart, encased within a closed back, reflects Rolex’s mastery of in-house engineering, ensuring reliability and precision that have become hallmarks of the brand. The Rolesor construction, a hallmark of the Datejust lineage, underscores the collection’s legacy as a bridge between tradition and innovation, offering a wearable testament to craftsmanship that transcends trends. Suited for the discerning collector who values understated luxury, this watch is equally at home in the boardroom or on the wrist of a connoisseur seeking a timepiece that balances heritage with contemporary relevance. Its quiet authority makes it an enduring companion for moments that demand both presence and restraint.

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.

178243-0067 is one of 31 executions of the 178243 base reference. Underneath they are the same watch; what separates this one is a white 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.
