Rolex Datejust 31 31 mm 278240SSJ Steel Silver

The Rolex Datejust is widely regarded as the archetype of the classic dress watch — a timepiece that has graced the wrists of world leaders, artists, and tastemakers since its debut in 1945 as the first self-winding wristwatch to display the date in a window at 3 o'clock. The Datejust 31 sits at the heart of this storied lineage, sized at 31mm to offer a refined, versatile fit that works equally well for smaller wrists seeking understated luxury or anyone who prefers a more classic mid-size silhouette on the wrist.

Reference 278240SSJ distills the essence of the Datejust into an immaculately finished package. The 31mm stainless steel case is crafted from Rolex's proprietary Oystersteel, renowned for its exceptional corrosion resistance and brilliance. The stainless steel domed bezel frames the dial with architectural simplicity, a hallmark of the clean Datejust aesthetic that never overpowers and never goes out of style.

The silver dial is one of the most enduringly popular choices in the Datejust family — luminous, legible, and effortlessly elegant. Silver dials catch light beautifully under any conditions, pairing seamlessly with formal attire and smart casual wear alike. The classic Datejust dial layout, with its characteristic date window and Cyclops lens, ensures instant readability while maintaining that signature Rolex poise.

The Jubilee bracelet is arguably the most celebrated of all Rolex bracelets, introduced alongside the very first Datejust in 1945. Its five-piece link construction and distinctive center links give it a fluid, jewellery-like drape on the wrist that is both supremely comfortable and unmistakably luxurious. On the 278240SSJ the bracelet is rendered in Oystersteel, lending cohesion and a polished, all-steel aesthetic from lug to clasp.

Powering the watch is a Rolex automatic movement, delivering the precise, self-winding reliability that collectors and daily wearers have trusted for generations. The watch also offers water resistance to 100 meters (330 feet), underscoring the Oyster case's robust, hermetically sealed construction and making the 278240SSJ a true companion for an active lifestyle as well as formal occasions.
