Rolex Datejust 31 31 mm 278274SDJ Steel/White Gold Silver Rolex Datejust 31 31 mm 278274SDJ Steel/White…

The Rolex Datejust is widely regarded as the archetype of the classic dress watch, a reference lineage that dates to 1945 when Rolex introduced the world's first self-winding wristwatch to display the date in a window at 3 o'clock. Over eight decades, the Datejust has remained in continuous production, evolving in proportion and material refinement while preserving the instantly recognizable silhouette that made it a cultural touchstone. The 31mm format occupies the sweet spot in Rolex's Datejust family — larger than the traditional 28mm Lady-Datejust, yet distinctly more refined than the full 36mm or 41mm gents' models — making it the preferred choice for wearers who want a meaningful dial presence without an oversized case.

Reference 278274SDJ is built on a case crafted from Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional corrosion resistance and high-polish luster, paired with 18k white gold to elevate the aesthetic into genuine luxury territory. The white gold appears most prominently in the fluted bezel, a signature Rolex design element whose precisely machined grooves catch light at every angle and immediately communicate that this is no ordinary timepiece. The combination of cool-toned white gold and Oystersteel creates a cohesive, all-white-metal palette that feels modern yet timeless.

The silver dial at the heart of the 278274SDJ contributes to the watch's serene, legible character. Silver dials in Rolex's vocabulary are typically engineered to a mirror or sunray finish that shifts tonally under different lighting conditions — appearing crisp white under bright light and taking on subtle warmth in shadow — lending depth and visual interest without disrupting the watch's understated confidence. Applied hour markers and the characteristic Datejust date window at 3 o'clock complete the dial in Rolex's considered, unhurried style.

The Jubilee bracelet that ships with the 278274SDJ is another storied detail. Introduced alongside the original Datejust in 1945 and named in honor of Rolex's fortieth anniversary, the five-piece link Jubilee bracelet is renowned for its exceptional suppleness and comfort on the wrist. Crafted to match the case in Oystersteel and white gold, the bracelet integrates seamlessly with the case design and drapes naturally, making the watch equally pleasant to wear for an afternoon meeting or an evening event. An Oysterlock safety clasp with Easylink comfort extension provides secure fastening and micro-adjustable sizing.

Powering the Datejust 31 is an automatic movement — Rolex's hallmark of mechanical self-sufficiency. Rolex calibers fitted to this reference are assembled and finished in-house to Superlative Chronometer standards, meaning each watch is certified for precision performance well beyond the requirements of the official COSC chronometer designation. Water resistance to 100 meters (330 feet) is delivered by the screw-down Triplock crown and Oyster case architecture, ensuring the watch is thoroughly protected for everyday wear including swimming and incidental splashing.
