Rolex Lady-Datejust 31 31 mm 278243SRDVIO Steel/Yellow Gold Silver Rolex Lady-Datejust 31 31 mm 278243SRDVIO Steel/Yellow…

The Rolex Lady-Datejust is one of the most storied timepieces in horological history, representing the world's first self-winding waterproof wristwatch designed specifically for women when it was introduced in 1957. Built on the legacy of the original Datejust—itself a landmark 1945 release that celebrated Rolex's 40th anniversary—the Lady-Datejust has evolved over decades while preserving its defining elegance: the cyclops-lens date window at three o'clock, the Oyster case, and the seamless integration of precious metals. Reference 278243SRDVIO in the 31 mm configuration represents the contemporary expression of that heritage, sized precisely between the 28 mm and the full 36 mm Datejust for women who prefer a modern, slightly bolder presence on the wrist.

The case and bracelet construction of this reference marry Oystersteel—Rolex's proprietary 904L stainless steel alloy celebrated for its exceptional corrosion resistance and high-polish retention—with yellow gold. Yellow gold on the Datejust has long signaled warmth and refinement, and on reference 278243SRDVIO it appears on the domed bezel and across the two-tone Oyster bracelet, creating a rich visual rhythm that catches light from every angle. The Oyster bracelet itself is one of Rolex's most recognized designs, valued for its durability, comfortable articulation, and secure folding Crownclasp.

The silver dial of the 278243SRDVIO is the visual centerpiece of the watch. Silver dials on the Lady-Datejust are perennially sought after because they pair effortlessly with the warmth of yellow gold, reading as simultaneously classic and contemporary. The clean, uncluttered dial architecture—characteristic of the Lady-Datejust family—ensures legibility while projecting understated luxury. The yellow gold domed bezel frames the dial with a gentle convex profile that complements the case proportions perfectly and has been a signature aesthetic choice on Datejust references for generations.

Powering this Lady-Datejust 31 is a Rolex automatic movement, the brand's in-house self-winding caliber technology that Rolex has refined continuously since first introducing the Perpetual rotor in 1931. The Oyster case provides a hermetic seal that protects the movement against dust, pressure, and water to a depth of 100 meters (330 feet)—a specification that comfortably accommodates swimming and everyday exposure to water while reassuring the owner of genuine robustness beneath the jewel-like exterior. The combination of automatic winding convenience and Oyster-level protection is a core reason the Lady-Datejust remains a benchmark of functional luxury.

For collectors and first-time buyers alike, reference 278243SRDVIO represents a compelling acquisition. The 31 mm two-tone configuration in steel and yellow gold with a silver dial is among the most versatile and universally flattering in the entire Datejust catalogue, dressing up or down with ease and holding its desirability across changing trends.
