Datejust 31 Rose Gold / Domed / Butterfly / Oyster

About This Watch

The Rolex Datejust 31 Reference 278245-0019 embodies the quiet sophistication of a timepiece that balances heritage with contemporary refinement. Within the Datejust collection—a lineage established in 1945 as a symbol of enduring elegance—this model distinguishes itself through its rose gold case, which exudes warmth and understated opulence. The domed sapphire crystal, paired with a white mother-of-pearl dial, creates a luminous interplay of light and texture, its gloss finish reflecting the precision of Rolex’s craftsmanship. The absence of indexes and the minimalist stick hands further emphasize the dial’s clean, uncluttered aesthetic, allowing the natural iridescence of the mother-of-pearl to take center stage. At its core, the watch is powered by Rolex’s in-house automatic movement 2236, a marvel of engineering that ensures precise timekeeping and a date display positioned for optimal readability. The Oyster case, with its closed back and 100-meter water resistance, reinforces the brand’s commitment to durability without compromising aesthetics. The butterfly clasp, a hallmark of modern Rolex design, ensures secure wear while maintaining the sleek profile that defines the Datejust 31’s appeal. This timepiece is for the discerning individual who values subtlety over ostentation, seeking a watch that transitions seamlessly from boardroom to evening engagements. It is not a statement, but a testament—a quiet assertion of legacy, precision, and timeless taste.

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.

278245-0019 is one of 24 executions of the 278245 base reference. Underneath they are the same watch; what separates this one is a white gloss 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.
