Datejust 31 Rose Gold / Domed / Rose - Roman / Oyster

About This Watch

The Rolex Datejust 31, in its rose gold iteration, embodies the quiet authority of a timepiece that has defined elegance for generations. With a 31-millimeter case, the watch strikes a balance between intimacy and presence, its domed form lending a sense of fluidity to the classic Oyster case architecture. The dial, a deep rose hue with a sunburst finish, glows with subtle depth, its Roman numerals and stick hands rendered in a restraint that underscores the Datejust’s enduring appeal. This reference, part of a collection first introduced in 1945, carries the weight of a legacy that has consistently married precision with poise, its design language refined over decades yet never outdated. Beneath the sapphire crystal lies the Caliber 2236, a self-winding movement that exemplifies Rolex’s mastery of mechanical engineering. Its 288-component construction, coupled with a 48-hour power reserve, ensures reliability without sacrificing the brand’s signature horological rigor. The closed case back, while discreet, hints at the craftsmanship within—a silent testament to the watch’s role as both a tool and a symbol. This watch is for those who value understated sophistication, whose presence is marked not by excess but by the quiet confidence of a timepiece that has withstood the test of time. It suits the boardroom, the gala, or the quiet moments in between, its rose gold hue a nod to tradition that feels both timeless and entirely contemporary.

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. 55 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.

278245-0033 is one of 24 executions of the 278245 base reference. Underneath they are the same watch; what separates this one is a rose sunburst dial and a rose gold case.

The 2236 is the Rolex movement inside more watches in this library than any other: 907, in the 28 mm Lady-Datejust and the 31 mm Datejust 31. It was the first Rolex caliber with a silicon hairspring. Introduced in 2014 in the Pearlmaster 34, it is a 20 mm automatic with a date, 31 jewels, a 55-hour reserve and a beat of 28,800 vph, certified by the COSC and then tested again by Rolex after casing to the Superlative Chronometer tolerance of two seconds a day. Its distinction is the Syloxi hairspring: silicon, immune to magnetism, etched to a patented geometry that keeps the spring concentric in every position, and paired with Paraflex shock absorbers. The larger Rolex calibers kept the Parachrom alloy spring; Syloxi did not reach a men's movement until the 7140 of 2023. The [2236 piece](/blog/the-rolex-2236-the-most-common-movement-in-this-library) sets out that history. In the library it powers 488 [Datejust 31](/brands/rolex/datejust-31) references, the seven-digit 2782xx generation of 2020, 399 [Lady-Datejusts](/brands/rolex/lady-datejust) of the 2791xx generation of 2015, 15 [Pearlmasters](/brands/rolex/pearlmaster) and 5 [Yacht-Master 37s](/brands/rolex/yacht-master). The [2235](/calibers/rolex-2235) is the 48-hour movement it replaced, the [2232](/calibers/rolex-2232) its no-date sibling for the Oyster Perpetual, and the [3235](/calibers/rolex-3235) its counterpart in the 36 mm and 41 mm cases.
