Datejust 31 Yellow Gold Fluted / Oyster / Champagne Floral

About This Watch

The Rolex Datejust 31, in its yellow gold fluted variant with a champagne floral dial, embodies the quiet authority of a timepiece that has defined elegance since its introduction in 1945. The 31mm case, crafted in 18ct yellow gold, exudes warmth and refinement, its fluted bezel a nod to the enduring design language that has graced Rolex’s most iconic references. The dial, a sunburst-finished champagne hue, is understated yet luminous, its absence of traditional indexes and use of stick hands emphasizing a minimalist, almost architectural clarity. This iteration of the Datejust 31, with its closed case back and sapphire crystal, balances the collection’s heritage of precision with a modern restraint that feels both timeless and deliberate. At its heart lies the Caliber 2235, a self-winding movement with a 55-hour power reserve, its Côtes de Genève decoration and concentric oscillating weight a testament to Rolex’s commitment to mechanical artistry. The watch’s 100-meter water resistance and Oyster case construction ensure it is as functional as it is beautiful, a paradox that has long defined the brand’s appeal. This watch is for the individual who values subtlety over ostentation, whose presence is marked not by volume but by precision. It suits the boardroom, the gala, or the quiet moments in between—where a watch is not merely worn, but quietly affirmed as a companion to a life of discernment.

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.

178278-0137 is one of 37 executions of the 178278 base reference. Underneath they are the same watch; what separates this one is a champagne sunburst 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.
