Datejust 31 Rolesor Yellow Fluted / Oyster / Silver Computer

About This Watch

The Rolex Datejust 31 in Rolesor — a harmonious blend of yellow gold and stainless steel — embodies the brand’s mastery of material synthesis and timeless design. This reference, distinguished by its 31mm case and fluted bezel, carries the legacy of the Datejust collection, which has long symbolized the intersection of elegance and precision since its introduction in 1945. The silver dial, adorned with gem-set indexes and complemented by sleek stick hands, exudes understated sophistication, while the Oyster case ensures resilience without compromising the watch’s refined silhouette. The sapphire crystal, paired with a closed case back, protects the intricate mechanics within, allowing the wearer to appreciate the seamless integration of form and function. At its core lies the Caliber 2235, an automatic movement certified as a chronometer for its accuracy and reliability. This movement, with its Parachrom balance spring and Paraflex shock absorbers, reflects Rolex’s commitment to engineering excellence, ensuring the watch performs with precision under any condition. The 100-meter water resistance further underscores its practicality, making it as suited for everyday wear as it is for formal occasions. This watch is for those who value discretion as much as craftsmanship, seeking a timepiece that transcends trends while honoring tradition. It is the quiet assertion of discernment, ideal for moments that demand both presence and restraint — whether in boardrooms, at cultural events, or on the wrist of someone who understands the language of subtlety.

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.

178273-0010 is one of 32 executions of the 178273 base reference. Underneath they are the same watch; what separates this one is a silver 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.
