Datejust 31 Rolesor Yellow Diamond / Oyster / Silver Roman

About This Watch

The Rolex Datejust 31, in its Rolesor Yellow Diamond configuration, stands as a masterclass in restrained opulence, blending the brand’s enduring craftsmanship with a refined, contemporary silhouette. The case, a harmonious union of yellow gold and stainless steel, reflects Rolex’s signature Rolesor technique, while the 31mm diameter offers a balanced presence that feels both intimate and commanding. At its heart lies a silver dial adorned with Roman numeral indexes and slender stick hands, a design language that echoes the Datejust collection’s mid-20th-century origins—when it first introduced the date complication to the wristwatch world. The dial’s understated elegance is complemented by the sapphire crystal and the Oyster caseback, ensuring durability without compromising the watch’s timeless aesthetic. Powering this timepiece is the Caliber 2235, a self-winding movement with a 70-hour power reserve, featuring a Parachrom balance spring and a blue Parachrom hairspring for exceptional precision and resistance to magnetic interference. These technical refinements underscore Rolex’s commitment to reliability, a legacy the Datejust has upheld since its debut in 1945. The watch’s closed caseback and water resistance to 100 meters further emphasize its practicality, marrying the elegance of a dress watch with the resilience of a sports model. This reference is for the discerning individual who values subtlety over ostentation, seeking a timepiece that exudes quiet confidence. It suits the boardroom, the gala, or the quiet moments between them—worn as a testament to heritage, precision, and the quiet assurance of a watch that needs no introduction.

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.

178383-0019 is one of 33 executions of the 178383 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.
