Datejust 31 Yellow Gold Fluted / Oyster / Silver

About This Watch

The Rolex Datejust 31, in its 178278-0034 iteration, embodies the enduring elegance of a collection first introduced in 1945, a timepiece that has since become a symbol of timeless sophistication. This particular model, crafted in yellow gold, marries the brand’s legacy of precision with a refined aesthetic that balances classicism and modernity. The fluted bezel, a hallmark of the Datejust lineage, frames a silver dial adorned with stick indexes and hands that exude clarity and restraint. The case, polished to a mirror-like sheen, is both robust and understated, its 31-millimeter diameter offering a presence that is neither ostentatious nor diminutive. Encased in an Oyster construction with a sapphire crystal and a closed case back, it is engineered for durability without sacrificing the delicate interplay of light and texture that defines Rolex’s craftsmanship. At its heart lies the Caliber 2235, an in-house automatic movement that ensures precise timekeeping with a date display positioned at the traditional 6 o’clock mark. The movement’s reliability and the watch’s 100-meter water resistance underscore its practicality, a quiet testament to Rolex’s commitment to function as much as form. The silver dial, paired with the warm hue of the yellow gold, creates a harmony that is both versatile and distinctive, suitable for occasions ranging from formal dinners to quiet moments of contemplation. This watch is for those who value heritage without harking back, who seek a piece that transcends trends yet remains unmistakably rooted in tradition. It is an object of quiet confidence, designed for the discerning individual who wears their legacy with subtlety.

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.

178278-0034 is one of 37 executions of the 178278 base reference. Underneath they are the same watch; what separates this one is a silver dial and a yellow gold case.

+ 28 more variants in this family.

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.
