Datejust 31 Everose Domed / President / Black Roman

About This Watch

The Rolex Datejust 31, in its Everose gold iteration with a black dial, embodies the quiet authority of a timepiece that has defined elegance for generations. This particular reference, distinguished by its domed case and President bracelet, merges the enduring sophistication of the Datejust collection with the warm, enduring hue of Everose gold—a proprietary alloy that resists tarnish and deepens in patina over time. The black dial, adorned with Roman numerals and sleek stick hands, offers a striking contrast to the rose-gold case, while the sapphire crystal ensures clarity and durability. The collection’s heritage, first introduced in 1945 as a response to the demand for a self-winding watch with a date display, is honored here through meticulous attention to detail, from the polished edges of the case to the seamless integration of the bracelet’s five-link design. At its heart lies the Caliber 2235, an automatic movement that combines precision with reliability, featuring a Parachrom balance spring and a 70-hour power reserve. The watch’s 100-meter water resistance and closed case back underscore its commitment to both function and discretion. This is a piece for those who value understated refinement, suited to moments that demand both presence and restraint—whether in the boardroom, at a gala, or during a quiet evening of reflection. It is not a statement, but a testament: to craftsmanship, to legacy, and to the quiet confidence of a watch that needs no embellishment to command respect.

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-0037 is one of 17 executions of the 178245f base reference. Underneath they are the same watch; what separates this one is a black 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.
