Datejust 31 Everose Domed / President / Brown MOP Roman

About This Watch

The Rolex Datejust 31, in its Everose gold iteration with a brown mother-of-pearl dial, embodies the quiet authority of a timepiece that has defined elegance for generations. Introduced in 1945, the Datejust collection remains one of Rolex’s most enduring designs, its clean lines and balanced proportions a testament to the brand’s commitment to timeless sophistication. This particular reference, with its domed case and President bracelet, marries the heritage of the Datejust with a contemporary refinement. The dial’s warm, caramel-hued mother-of-pearl surface shimmers with subtle depth, its Roman numerals and slender stick hands echoing the understated precision of the collection’s original vision. The Everose gold, a proprietary alloy developed by Rolex, lends the case a rich, enduring patina that resists tarnish, ensuring the watch retains its luster over decades of wear. At its heart lies the Caliber 2235, a self-winding movement with a 70-hour power reserve, featuring a Parachrom balance spring and a Perpetual rotor that ensures reliability and accuracy. The sapphire crystal, paired with a water resistance of 100 meters, underscores the watch’s practicality without compromising its aesthetic restraint. The President bracelet, with its five-link design and concealed clasp, offers a seamless blend of comfort and luxury, a hallmark of Rolex’s craftsmanship. This watch is for the individual who values heritage as much as horology, whose presence is marked by quiet confidence. It suits occasions that demand both formality and discretion, yet its versatility makes it equally at home in the boardroom or on a weekend stroll. A Datejust 31 is not merely an accessory—it is a legacy in the making.

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-0021 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.
