Datejust 31 Rolesor Everose Domed Diamond / Jubilee / Silver Computer

About This Watch

The Rolex Datejust 31 178341-0045 stands apart within the collection’s storied lineage through its harmonious blend of materials and refined detailing. This particular iteration marries the brand’s signature Rolesor construction—rose gold and stainless steel—into a 31mm case that balances presence with subtlety. The dial, a luminous silver backdrop, is elevated by gem-set indexes that catch light with quiet precision, while stick hands add a timeless clarity to the design. The domed sapphire crystal, paired with a closed case back, encases the watch’s mechanical heart without compromising the clean, uncluttered aesthetic that defines the Datejust’s enduring appeal. At its core, the 2235 movement—a self-winding chronometer certified by COSC—ensures precision and reliability, its Parachrom balance spring offering resilience against magnetic interference. This technical sophistication is married to the collection’s heritage, first introduced in 1945 as a symbol of enduring elegance. The Jubilee bracelet, with its five-link design, complements the watch’s polished silhouette, ensuring comfort as much as style. Suited for those who value understated sophistication, this watch thrives in moments that demand both discretion and distinction: a boardroom meeting, a gala, or simply the quiet confidence of daily wear. It is a testament to Rolex’s mastery of blending heritage with innovation, offering a piece that transcends trends while remaining perpetually relevant.

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.

178341-0045 is one of 34 executions of the 178341 base reference. Underneath they are the same watch; what separates this one is a silver dial and a rose gold, stainless steel 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.
