Datejust 31 Stainless Steel Diamond / Jubilee / Pink - Diamond

About This Watch

The Rolex Datejust 31, in its 178384-0045 iteration, marries the enduring elegance of the Datejust collection with a contemporary reinterpretation of luxury. Introduced in 1945 as a timepiece designed to accommodate the date display on the dial, the collection has long been a symbol of understated sophistication. This particular reference elevates the design with a striking pink dial, its hue both warm and refined, framed by gem-set indexes that catch light with subtle brilliance. The combination of stainless steel and white gold in the case adds a tactile richness, while the Jubilee bracelet—characteristic of the Datejust—offers a balance of comfort and structural integrity. The stick hands, paired with the sapphire crystal, ensure clarity and precision, reflecting the watch’s commitment to both aesthetics and function. At its core, the 2235 automatic movement delivers the reliability and accuracy for which Rolex is renowned, featuring a Parachrom hairspring and a self-winding mechanism that ensures consistent performance. The closed case back, water resistance to 100 meters, and the 31mm diameter make this a versatile yet distinctly feminine proposition within the Datejust lineage. This watch is for those who value heritage without compromise, seeking a piece that transcends trends while honoring tradition. It suits occasions that demand both presence and restraint—a gala, a private meeting, or simply a moment of quiet confidence worn on the wrist.

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.

178384-0045 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.
