Datejust 31 Rolesor Everose Domed Diamond / Oyster / MOP

About This Watch

The Rolex Datejust 31, in its Rolesor iteration with an Everose gold case and a domed Mother of Pearl dial, embodies the quiet sophistication of a timepiece that has defined elegance for generations. Introduced in 1945, the Datejust collection established itself as a benchmark for luxury watches, blending precision with timeless design. This particular reference, with its 31mm case and gem-set indexes, captures the essence of understated opulence—its white Mother of Pearl dial, kissed by the subtle interplay of light through the sapphire crystal, evokes a sense of enduring refinement. The stick hands and polished diamond bezel add a touch of restraint, ensuring the watch remains a focal point without overt display. At its core, the 178341-0018 is powered by the Caliber 2235, a self-winding movement renowned for its reliability and chronometric certification. This mechanical heart, with its 288 components and 28,800 vibrations per hour, ensures precision that aligns with Rolex’s legacy of engineering excellence. The Oyster case, sealed against water and wear, reinforces the watch’s durability, a hallmark of the brand since 1926. For those who value heritage as much as craftsmanship, this Datejust 31 is a companion for moments that demand both presence and discretion—whether at a black-tie gala, a private dinner, or as a quiet testament to legacy on the wrist. It is not a statement, but a signature.

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.

178341-0018 is one of 34 executions of the 178341 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.
