Datejust 31 Stainless Steel Diamond / Oyster / Pink - Roman

About This Watch

The Rolex Datejust 31, a perennial symbol of understated elegance, finds a striking expression in this particular iteration, distinguished by its harmonious blend of materials and a dial color that commands quiet attention. The pink dial, a rare and deliberate choice, evokes a sense of warmth and sophistication, framed by stick indexes and hands that enhance its legibility without intruding on its refined aesthetic. Encased in a combination of white gold and stainless steel, the watch balances the weight of tradition with the precision of modern craftsmanship, its 31mm diameter ensuring a presence that is neither ostentatious nor diminutive. The Oyster case, paired with a sapphire crystal, underscores Rolex’s commitment to durability and clarity, while the closed case back invites contemplation of the mechanical artistry within. At the heart of this timepiece lies the Caliber 2235, a self-winding movement celebrated for its reliability and the precision of its date display, a feature that has defined the Datejust collection since its introduction in 1945. This iteration, like its predecessors, marries the brand’s heritage of innovation with a design that

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.

178384-0024 is one of 52 executions of the 178384 base reference. Underneath they are the same watch; what separates this one is a pink 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.
