Datejust 31 Rolesor Yellow Diamond / Oyster / Silver Diamond

About This Watch

The Rolex Datejust 31, in its Rolesor Yellow Diamond iteration, embodies a refined equilibrium of tradition and innovation, distinguishing itself through its harmonious blend of yellow gold and stainless steel. The 31mm case, a size that has become synonymous with the collection’s enduring appeal since its introduction in 1945, is adorned with a dial that captures the quiet elegance of sunburst-finished silver. Its gem-set indexes, meticulously arranged, add a subtle yet unmistakable touch of opulence, while the stick hands maintain the Datejust’s hallmark legibility and restraint. This particular reference, with its polished interplay of precious metals and the precision of its Oyster case, reflects the Datejust’s legacy as a timepiece that bridges the gap between formal sophistication and enduring wearability. At its core lies the Caliber 2235, a self-winding movement celebrated for its reliability and the inclusion of a chronometer certification, ensuring accuracy under varied conditions. The sapphire crystal, paired with a closed case back, reinforces the watch’s robustness without compromising its aesthetic purity. The 100-meter water resistance, though not a feature typically emphasized in this collection, underscores the Datejust’s practicality for everyday life. This watch is for the individual who values heritage without ostentation, seeking a piece that commands respect through subtlety rather than excess. It is suited to moments that demand both presence and discretion—whether in the boardroom, at a gala, or worn casually as a testament to enduring craftsmanship.

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.

178383-0041 is one of 33 executions of the 178383 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.
