Rolex Datejust 36 36 mm 126231SRJ Steel/Rose Gold Slate Rolex Datejust 36 36 mm 126231SRJ Steel/Rose…

The Rolex Datejust is one of the most enduring icons in watchmaking history, introduced in 1945 as the first self-winding wristwatch to display the date in a magnified window on the dial — a feature Rolex calls the Cyclops lens. Across nearly eight decades of continuous production the Datejust has remained the definitive benchmark of classic Swiss watchmaking, evolving in materials, dial configurations, and bracelets while preserving the instantly recognizable silhouette that has graced the wrists of heads of state, artists, and athletes alike. Reference 126231SRJ represents the current-generation 36mm expression of that legacy, blending Rolex's most traditional proportions with some of its most refined finishing choices.

The 36mm Oyster case of the 126231SRJ is constructed in Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish — complemented by 18k Everose gold components. Everose is Rolex's own rose-gold alloy, formulated in-house to resist fading over time, and it appears here on the fluted bezel, giving the watch its signature two-tone warmth. The fluted bezel is one of the most storied design elements in the Datejust family, tracing its roots to the earliest references and serving both as an aesthetic flourish and as a subtle identifier of precious-metal content.

The dial of this 126231SRJ is finished in a deep slate hue and set with Roman numeral hour markers — a configuration sometimes referred to in the collector community as the Wimbledon dial for its aristocratic, court-ready character. Slate offers a cooler, more contemporary alternative to the warmer champagne and silver dials commonly associated with the Datejust, and the Roman numerals add a layer of classical formality that pairs beautifully with the rose-gold accents. The date window at three o'clock is fitted with Rolex's Cyclops magnification lens, a hallmark of every Datejust since the model's debut.

Power for the 126231SRJ is supplied by an automatic movement, keeping the watch running without the need for manual winding during regular wear. Rolex automatic calibers used in this generation of Datejust are manufactured entirely in-house and certified as Superlative Chronometers to standards exceeding the official Swiss COSC benchmark. The movement features Rolex's Perpetual rotor for efficient winding and a paramagnetic blue Parachrom hairspring for resilience against magnetic fields and shocks.

The Jubilee bracelet — a five-link design debuted alongside the very first Datejust in 1945 — completes the 126231SRJ and contributes substantially to its wrist presence. Crafted in matching Oystersteel and 18k Everose gold, the Jubilee is renowned for its supple drape and comfort across a broad range of wrist sizes, making the 36mm case an outstanding choice for any wearer who values a watch that wears beautifully all day without fatigue. The case is rated to 100 meters (330 feet) of water resistance, underpinning the Oyster case's reputation for robustness in everyday life.
