Rolex Lady-Datejust 31 31 mm 278273SDJ Steel/Yellow Gold Silver

Few watches have defined feminine luxury watchmaking as completely as the Rolex Lady-Datejust. Introduced as the first self-winding waterproof wristwatch scaled specifically for women, the Datejust lineage stretches back to 1945, and the 31mm case size sits at an ideal midpoint—substantial enough to be read with ease, refined enough to complement the most elegant wrist. Reference 278273SDJ represents the contemporary expression of that heritage, pairing the resilience of Oystersteel with the warmth of 18k yellow gold in a watch that is as technically serious as it is aesthetically compelling.

The two-tone Oystersteel and yellow gold construction of the 278273SDJ is one of the hallmarks of the Lady-Datejust's enduring appeal. Rolex's Oystersteel is drawn from the 904L alloy family, prized for its exceptional corrosion resistance and mirror-like polish, while the 18k yellow gold elements—bezel, crown, and bracelet center links—introduce a warmth that elevates the watch into genuine jewelry territory. The result is a 31mm case that photographs beautifully and ages even better, resisting the everyday wear that diminishes lesser materials.

Central to this reference is the yellow gold fluted bezel, one of the most recognizable motifs in all of horology. Originally conceived to tighten the bezel onto the case and exclude moisture, the fluted bezel evolved into a purely aesthetic signature, its faceted edges catching light in a way that few design elements can match. Paired with the silver dial, the combination is classically Rolex: restrained, perfectly proportioned, and instantly legible. The silver dial provides a clean, luminous backdrop that suits formal attire as naturally as it does business dress.

The Lady-Datejust 31 278273SDJ is worn on Rolex's iconic Jubilee bracelet—a five-piece link design introduced alongside the original Datejust in 1945 and widely regarded as one of the most comfortable metal bracelets ever made. Its supple, low-profile construction drapes the wrist with an ease that belies its solid construction, and in two-tone steel and yellow gold it reinforces the watch's dual identity as both a precision instrument and a luxury accessory. The Oyster clasp secures the bracelet with the same confidence that characterizes every element of this reference.

Inside the Oyster case, an automatic movement keeps time with the reliability that generations of Rolex wearers have come to expect, and the 100-meter (330-foot) water resistance rating means the watch performs equally well in daily life—whether caught in the rain or worn poolside. The certified authentic example offered here is brand new, ensuring it arrives in flawless factory condition with no prior wear.
