Datejust 31 Everose Domed / President / Silver Diamond

About This Watch

The Rolex Datejust 31, in its 178245f-0016 iteration, marries the brand’s enduring legacy with a refined modernity that speaks to the subtleties of horological craftsmanship. The everose gold case, a proprietary alloy renowned for its warm, enduring hue, is subtly domed—a nod to the Datejust’s original 1945 design while embracing a contemporary silhouette. Paired with the President bracelet, a hallmark of Rolex’s commitment to both comfort and prestige, the watch exudes a quiet authority. The dial, a luminous silver backdrop, is adorned with gem-set indexes that catch light with understated brilliance, while the stick hands trace their lineage to the earliest Datejust models, ensuring a timeless visual language. At its heart lies the Caliber 2235, an automatic movement distinguished by its chronometric certification and the inclusion of a Parachrom blue balance spring, a technical innovation that enhances precision and resilience. This mechanical sophistication is encased in a 31mm diameter that balances proportion and presence, a size choice that honors the Datejust’s role as a unisex icon since its inception. The sapphire crystal, paired with a closed case back, underscores the watch’s durability and the discreet elegance of its construction. This piece is for those who seek a timepiece that transcends trends, embodying both heritage and modernity. It is suited to moments of quiet distinction—whether in the boardroom, at a gala, or as a companion to life’s most significant milestones. Its value lies not in ostentation, but in the quiet confidence of a watch that has, for decades, defined the intersection of artistry and engineering.

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-0016 is one of 17 executions of the 178245f base reference. Underneath they are the same watch; what separates this one is a silver dial and a rose gold case.

+ 8 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.
