Datejust 31 Stainless Steel Fluted / Oyster / Bronze - Roman

About This Watch

The Rolex Datejust 31, in its 178274-0089 iteration, marries the enduring elegance of the Datejust collection with a striking reinterpretation of classic design. The bronze dial, a deliberate departure from traditional Rolex palettes, exudes a warm, patina-rich depth that evolves with time, while the fluted stainless steel bezel and white gold caseframe lend it a refined duality of materials. This reference retains the Datejust’s hallmark proportions—31mm diameter, 16mm lug width—ensuring a silhouette that balances modernity with the collection’s mid-20th-century heritage, first introduced in 1945 as a symbol of accessible luxury. The Roman numeral indexes and slender stick hands further underscore its adherence to timeless horological aesthetics, framed by a sapphire crystal that offers clarity without compromise. At its core, the watch is powered by Rolex’s in-house Caliber 2235, a self-winding movement with a 55-hour power reserve and a Parachrom blue balance spring, ensuring precision and resilience. The closed caseback, while discreet, emphasizes the Datejust’s focus on understated sophistication over ostentation. This watch is for the discerning individual who values heritage and craftsmanship, yet seeks a timepiece that carries a quiet, evolving character. It suits those who appreciate the subtlety of a dial that deepens with wear, or the quiet confidence of a watch that requires no introduction—only recognition.

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.

178274-0089 is one of 52 executions of the 178274 base reference. Underneath they are the same watch; what separates this one is a bronze dial and a white 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.
