Datejust 31 Everose Fluted / President / Chocolate Roman

About This Watch

The Rolex Datejust 31 178275f-0031 embodies the quiet authority of a timepiece that merges tradition with contemporary refinement. Its 31mm rose gold case, crafted from Rolex’s proprietary Everose gold, exudes a warm, enduring hue that deepens with wear, while the fluted bezel—a hallmark of the Datejust collection since its 1945 debut—adds a tactile, sculptural dimension to its profile. The dial, a rich chocolate brown with a sunburst finish, is framed by elegant Roman numerals and slender stick hands, creating a balance of legibility and restraint. Paired with the President bracelet, a symbol of Rolex’s mastery in metallurgy and comfort, the watch becomes a seamless fusion of heritage and modernity, suited to those who value understated sophistication. At its core lies the Caliber 2235, a self-winding movement with a date function that operates with the precision expected of a Swiss-made chronometer. Its 100-meter water resistance and

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.

178275f-0031 is one of 19 executions of the 178275f base reference. Underneath they are the same watch; what separates this one is a brown sunburst 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.
