Datejust 31 Rolesor Yellow Diamond / Oyster / Green Roman

About This Watch

The Rolex Datejust 31, in its Rolesor Yellow Diamond iteration, embodies a rare balance of tradition and innovation, distinguished by its harmonious union of yellow gold and stainless steel. This 31mm timepiece, with its green dial, evokes a quiet sophistication that resonates with those who value understated elegance. The dial’s deep green hue, framed by sleek Roman numerals and slender stick hands, is both legible and evocative, a nod to the Datejust collection’s enduring design language since its introduction in 1945. The use of yellow gold in the case, paired with the resilience of stainless steel, reflects Rolex’s mastery of metallurgy, while the sapphire crystal and 100-meter water resistance underscore its practicality without compromising its refined appearance. At its core lies the Caliber 2235, a self-winding mechanical movement that delivers precision and reliability, hallmark traits of Rolex’s engineering. The date display, positioned at the 6 o’clock mark, is seamlessly integrated into the dial’s composition, a detail that speaks to the brand’s commitment to functional aesthetics. This watch is for the discerning individual who seeks a timepiece that transcends trends, serving as both a daily companion and a statement of quiet authority. It suits formal occasions with its polished presence, yet its durability ensures it remains equally at home in more casual settings, a testament to Rolex’s ability to merge luxury with longevity.

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.

178383-0043 is one of 33 executions of the 178383 base reference. Underneath they are the same watch; what separates this one is a green 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.
