Datejust 31 Rolesor Yellow Fluted Diamond / Jubilee / White Roman

About This Watch

The Rolex Datejust 31 in Rolesor—yellow gold and stainless steel—embodies the enduring balance of tradition and refinement that defines the collection. Introduced in 1945, the Datejust has long been a benchmark for elegant, complication-driven timepieces, and this reference exemplifies its legacy with a harmonious blend of materials and design. The white dial, framed by a fluted diamond bezel, offers a striking contrast to the warm hue of the yellow gold, while the stick hands and Roman numeral indexes evoke a sense of quiet authority. The Jubilee bracelet, with its five-link design, enhances the watch’s wearability without compromising its formal demeanor, ensuring it transitions seamlessly from boardroom to evening engagement. At its core, the Datejust 31 houses the Caliber 2235, a self-winding movement with a 70-hour power reserve, reflecting Rolex’s commitment to precision and reliability. The sapphire crystal, paired with a closed case back, underscores the brand’s emphasis on durability and discretion. Measuring 31mm in diameter, the case strikes a refined equilibrium between presence and subtlety, a hallmark of Rolex’s approach to horology. This watch is for those who value understated sophistication and the quiet confidence of a timepiece that requires no explanation. It suits occasions where heritage and craftsmanship are as important as aesthetics, serving as both a functional instrument and a testament to enduring 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.

178313-0062 is one of 31 executions of the 178313 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.
