The Details
Craftsmanship & Specifications
A Harmonious Balance of Proportions
The Datejust 31 occupies a unique position in the Rolex catalog, offering a mid-size alternative that provides more presence than the Lady-Datejust while maintaining a slender, feminine silhouette. The reference 278274 represents a fusion of traditional watchmaking and modern materials, housed in a 31mm Oyster case that is water-resistant to 100 meters.
The Radiance of White Rolesor
White Rolesor is a signature Rolex combination that pairs the brilliance of 18k white gold with the ruggedness of Oystersteel. In the 278274, the fluted bezel is crafted from solid white gold, serving as a hallmark of Rolex distinction and a focal point for the watch’s aesthetic. The dial is protected by a scratch-resistant sapphire crystal and the iconic Cyclops lens, which magnifies the date at 3 o’clock for effortless reading throughout the day.
Innovation in the Calibre 2236
At the heart of the 278274 is the Calibre 2236, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement is the first to incorporate the Syloxi hairspring in silicon, which is patented by the brand. The Syloxi hairspring is completely insensitive to magnetic interference and remains up to ten times more precise than a traditional hairspring when subjected to shocks. Its geometry ensures regular oscillations in any position, providing the watch with Superlative Chronometer accuracy of −2/+2 seconds per day.
Refined Bracelet Options
This reference is typically presented on either the elegant five-piece link Jubilee bracelet or the robust three-piece link Oyster bracelet. Both styles are designed to offer a secure and comfortable fit, featuring the Oysterclasp and the Easylink comfort extension. This system allows the wearer to easily increase the bracelet length by approximately 5mm, providing immediate relief should the wrist expand due to temperature or activity.
