Datejust 31 Rolesor Yellow Domed / Oyster / Champagne Computer

About This Watch

The Rolex Datejust 31, in its Rolesor iteration of yellow gold and stainless steel, embodies the quiet authority of a timepiece that has defined elegance for generations. This particular model, with its domed yellow gold case and champagne dial, strikes a balance between tradition and modernity, its 31mm diameter offering a refined presence that feels both intimate and commanding. The dial, a soft champagne hue, is elevated by gem-set indexes that catch light with subtle precision, while the stick hands trace their path with unobtrusive clarity. The combination of materials—yellow gold’s warmth against the coolness of stainless steel—echoes the Datejust’s legacy as a symbol of enduring sophistication, first introduced in 1945 as a watch for men who demanded both precision and prestige. At its heart lies the Caliber 2235, an automatic movement that marries Rolex’s commitment to in-house engineering with a date display that operates with the seamless reliability expected of the brand. The Oyster case, paired with a sapphire crystal, ensures durability without compromising the watch’s delicate aesthetic, while the closed case back invites contemplation of the craftsmanship hidden within. This is a timepiece that thrives in the interplay of light and shadow, its design language speaking to those who value subtlety over ostentation. For the discerning collector or the individual who seeks a companion for both formal occasions and moments of quiet reflection, this Datejust 31 is a testament to the enduring appeal of a watch that needs

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.

178243-0027 is one of 31 executions of the 178243 base reference. Underneath they are the same watch; what separates this one is a champagne 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.
