Datejust 31 Stainless Steel Domed Diamond / Oyster / Pink

About This Watch

The Rolex Datejust 31, in its 178344-0052 iteration, marries the enduring elegance of the Datejust collection with a refined interplay of materials and color. The case, a harmonious blend of white gold and stainless steel, frames a dial of soft pink that exudes quiet sophistication. This hue, neither overtly bold nor subdued, complements the watch’s architectural lines and the subtle contrast of stick hands and dot indexes, which echo the Datejust’s mid-20th-century design language. A domed diamond bezel adds a touch of discreet opulence, while the Oyster case—water-resistant to 100 meters—ensures resilience without compromising the watch’s svelte 31mm profile. The closed case back, a hallmark of Rolex’s commitment to precision, encases the Calibre 2235, an in-house automatic movement celebrated for its reliability, chronometer certification, and the smooth, sweeping motion of its balance wheel. As one of the most enduring collections in horology, the Datejust has long symbolized the intersection of tradition and innovation. Introduced in 1945, its design has remained a touchstone for timeless aesthetics, and this reference honors that legacy with a contemporary twist. The pink dial, though rare in the Datejust lineup, offers a fresh interpretation of the collection’s signature elegance, suited to those who seek distinction without ostentation. This watch is for the discerning individual who values understated craftsmanship

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.

178344-0052 is one of 51 executions of the 178344 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.
