Datejust 31 Stainless Steel Fluted / Jubilee / Pink MOP Roman

About This Watch

The Rolex Datejust 31, in its 178274-0044 iteration, embodies the quiet authority of a timepiece that has defined elegance since its introduction in 1945. This reference distinguishes itself through a dial that marries rarity with refinement: a pink mother-of-pearl surface, its iridescence shifting subtly under light, framed by polished gold Roman numerals and slender stick hands that emphasize precision without ostentation. The fluted bezel, a hallmark of the Datejust lineage, adds a tactile and visual contrast to the dial’s soft radiance, while the Jubilee bracelet—its five-link design a nod to the 1950s—offers a balance of comfort and sophistication. At its core, the watch is powered by Rolex’s Caliber 2235, an automatic movement renowned for its reliability and the inclusion of a Parachrom balance spring, which ensures accuracy even under extreme conditions. The closed caseback and sapphire crystal further underscore the brand’s commitment to durability and clarity, allowing the wearer to appreciate the craftsmanship without compromise. The 31mm case, though modest in size, is proportioned with the precision of decades of horological expertise, making it a versatile companion for both formal engagements and quiet moments of introspection. This watch is for the discerning individual who values heritage as much as horology, seeking a piece that transcends trends yet remains unmistakably timeless. It is suited to those who prefer their luxury to speak in subtleties—a quiet assertion of status, worn with the confidence of knowing its legacy.

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.

178274-0044 is one of 52 executions of the 178274 base reference. Underneath they are the same watch; what separates this one is a pink dial.

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.
