Datejust 31 Rolesor Everose Domed / Jubilee / MOP Roman

About This Watch

The Rolex Datejust 31, in its 178241-0057 iteration, marries the brand’s legacy of precision with a refined aesthetic that nods to the collection’s enduring appeal since its introduction in 1945. The dial, a luminous mother-of-pearl surface, captures and diffuses light with a subtle iridescence, its radiance complemented by the understated elegance of Roman numerals and slender stick hands. Encased in 18ct Everose gold, the domed case and Jubilee bracelet evoke the timeless proportions of the original Datejust, while the 31mm diameter ensures a modern, wearable presence. The sapphire crystal, paired with a closed case back, emphasizes the watch’s robust construction, its 100-meter water resistance a quiet testament to practicality without compromising sophistication. At its heart lies the Caliber 2235, an automatic movement with a date display and a power reserve of approximately 55 hours. Its finishing—perlage on the oscillating weight, polished angles on the bridges—reflects Rolex’s commitment to horological craftsmanship, even in the smallest details. The watch’s heritage is further underscored by its role as a bridge between the Datejust’s mid-20th-century origins and contemporary expectations of luxury, where tradition and innovation coexist seamlessly. This timepiece is for those who value discretion as much as heritage, a statement piece suited to formal occasions yet equally at home in the quiet confidence of daily life. It speaks to collectors who seek not only rarity but a connection to a lineage of excellence, where every detail is a nod to the past and a promise of enduring value.

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.

178241-0057 is one of 30 executions of the 178241 base reference. Underneath they are the same watch; what separates this one is a white dial.

+ 21 more variants in this family.

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.
