Datejust 31 Everose Domed / President / Chocolate Roman

About This Watch

The Rolex Datejust 31, in its 178245f-0032 iteration, embodies the quiet confidence of a timepiece that balances tradition with subtle innovation. The everose gold case, a signature alloy developed by Rolex for its warm, enduring hue, is shaped with a gently domed profile that echoes the brand’s mid-20th-century design language while retaining a modern elegance. Paired with a brown dial featuring Roman numerals and slender stick hands, the watch exudes a refined restraint, its chocolate-toned surface deepened by the contrast of the gold indices and the lume-filled hour markers. The President bracelet, with its five-link construction and polished finish, adds a layer of sophistication that complements the dial’s understated warmth, ensuring both comfort and a sense of occasion. As the flagship model of the Datejust collection—a line first introduced in 1945 to commemorate Rolex’s 40th anniversary—the 31mm case size offers a more intimate presence without sacrificing the brand’s hallmark precision. At its heart lies the Caliber 2235, an automatic movement certified as a chronometer for its accuracy and reliability, paired with a date display that operates seamlessly through the sapphire crystal. The closed case back, while discreet, underscores the watch’s commitment to durability and craftsmanship. This piece is for the discerning individual who values subtlety over ostentation, a watch that commands respect through its quiet sophistication. It is suited to moments that demand both elegance and endurance: a boardroom meeting, a gala, or simply the quiet passage of time on one’s wrist.

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.

178245f-0032 is one of 17 executions of the 178245f base reference. Underneath they are the same watch; what separates this one is a brown dial and a rose gold 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.
