Datejust 31 White Gold - Diamond / Blue - Floral / President

About This Watch

The Rolex Datejust 31, in its 278289RBR-0025 iteration, embodies the quiet sophistication of a timepiece that balances tradition with subtle innovation. Within the Datejust collection—a lineage established in 1945 as Rolex’s first self-winding waterproof chronometer—this reference distinguishes itself through its striking blue dial, framed by a gem-set bezel that catches light with restrained elegance. The white gold case, polished to a mirror finish, encases a dial where the absence of traditional indexes allows the floral motif, rendered in delicate diamond-set detailing, to take center stage. This interplay of geometry and organic form reflects the Datejust’s enduring appeal: a design that remains timeless while embracing the artistry of its execution. At its core, the watch is powered by Rolex’s in-house 2236 automatic movement, a marvel of engineering that ensures precision and reliability without drawing attention to itself. The sapphire crystal, paired with a closed case back, underscores the watch’s commitment to both durability and discretion. The President bracelet, with its signature five-link design, wraps the wrist in a manner that is both secure and unobtrusive, a hallmark of Rolex’s approach to wearable luxury. This watch is for the individual who values understated refinement, someone whose taste is measured not by excess but by the quiet confidence of a well-crafted object. It suits occasions where presence matters more than proclamation—a gala, a boardroom, or a quiet moment of reflection—worn as much for its heritage as for its quiet, enduring beauty.

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.

278289RBR-0025 is one of 16 executions of the 278289RBR base reference. Underneath they are the same watch; what separates this one is a blue dial and a white 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.
