Datejust 31 Rolesor Yellow Fluted / Jubilee / White Roman

About This Watch

The Rolex Datejust 31 178273-0073 embodies the enduring balance of tradition and refinement that defines the Datejust collection, first introduced in 1945 as a symbol of timeless elegance. This particular iteration, crafted in Rolesor—a harmonious blend of yellow gold and stainless steel—exudes understated sophistication, with a fluted bezel and Jubilee bracelet that pay homage to the brand’s legacy of meticulous craftsmanship. The white dial, adorned with crisp Roman numerals and slender stick hands, offers a clean, legible aesthetic that remains unobtrusive yet distinguished, while the sapphire crystal ensures clarity and durability. At 31mm in diameter, the case strikes a refined proportion, complemented by a water resistance of 100 meters and a closed case back that emphasizes the watch’s discreet, enduring quality. Powering this timepiece is the in-house automatic movement 2235, a testament to Rolex’s engineering precision, featuring a Parachrom blue balance spring and a COSC-certified chronometer grade. The interplay of materials—yellow gold’s warmth against the coolness of stainless steel—echoes the Datejust’s role as a bridge between classic and contemporary horology. This watch is for the discerning individual who values heritage, subtlety, and the quiet confidence of a piece that requires no introduction. It suits moments that demand both presence and restraint, from formal gatherings to the quiet assurance of everyday distinction.

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.

178273-0073 is one of 32 executions of the 178273 base reference. Underneath they are the same watch; what separates this one is a white 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.
