Datejust 31 Rolesor Yellow Fluted / Oyster / Champagne Diamond

About This Watch

The Rolex Datejust 31 in Rolesor — a harmonious blend of yellow gold and stainless steel — embodies the enduring elegance of the Datejust collection, first introduced in 1945 as a symbol of accessible luxury. This particular iteration, with its fluted bezel and champagne dial, merges classic horological design with refined materiality. The dial’s warm, golden hue is accented by gem-set indexes that catch light with quiet subtlety, while the stick hands ensure legibility without intruding on the composition’s restraint. The Oyster case, sealed with a closed back, underscores Rolex’s commitment to durability, and the sapphire crystal protects the dial with unobtrusive clarity. At 31mm in diameter, the watch balances presence and discretion, its 16mm lug width ensuring a secure fit across a range of wrist sizes. Powering the timepiece is the Caliber 2235, a self-winding movement certified as a chronometer for precision. Its intricate finishing and reliability reflect Rolex’s mastery of mechanical engineering, while the 100-meter water resistance adds practicality to its sophistication. The Datejust 31’s heritage as a cornerstone of the brand’s identity — a watch that has accompanied generations of professionals and collectors — is evident in its unpretentious grandeur. This is a timepiece for those who value understated craftsmanship and timeless design, suited to both formal occasions and the quiet confidence of everyday wear. Its Rolesor construction and champagne dial make it a versatile companion, capable of transcending trends while remaining unmistakably Rolex.

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.

178273-0018 is one of 32 executions of the 178273 base reference. Underneath they are the same watch; what separates this one is a champagne dial and a yellow gold, stainless steel case.

+ 23 more variants in this family.

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.
