Rolex Lady-Datejust 26 179179-BLKDP Black Diamond Fluted White Gold President - BRAND NEW

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced in 1957 as the first self-winding waterproof wristwatch with a date display sized specifically for a woman's wrist. Over its decades of continuous production, the Lady-Datejust has become synonymous with refined elegance, precise Swiss engineering, and the kind of timeless design that transcends fashion cycles. Reference 179179-BLKDP represents the Lady-Datejust at its most luxurious, positioned squarely at the summit of the collection.

At 26mm in diameter, the case of the 179179-BLKDP is fashioned entirely from 18k white gold — a noble metal chosen for its cool luminosity, exceptional durability, and resistance to tarnishing. White gold flatters the wrist with a restrained yet unmistakably precious presence, and on this reference the metal appears on every surface: case, crown, bezel, and bracelet. The result is a cohesive, all-white-gold composition that reads as jewelry as much as it does as a watch.

The dial of the 179179-BLKDP is set with factory-installed black diamonds by Rolex's own gem-setting artisans in Geneva. The contrast between the deep, light-absorbing black of the diamond indices and the radiant white gold surround creates a dramatic chiaroscuro effect that is both bold and sophisticated. Because these diamonds are set at the factory by Rolex, they carry the brand's full authentication and guarantee — a critical distinction that aftermarket diamond-set dials simply cannot match.

The fluted bezel is one of the most recognized design signatures in all of horology. Originally conceived as a functional tool for tightening the case, the fluted bezel evolved into a symbol of Rolex prestige and is executed in 18k white gold on this reference, its precisely machined grooves catching and reflecting light from every angle. Paired with the three-link President bracelet — itself an icon introduced alongside the original Day-Date in 1956 — the watch wears as a complete, harmonious jewel on the wrist. The President bracelet's semi-circular links have a flowing, sculptural quality that makes it immediately identifiable and supremely comfortable.

Powering the Lady-Datejust is a certified Swiss-made automatic movement built to Rolex's exacting tolerances and certified as a Superlative Chronometer, a designation that reflects testing performed by Rolex beyond the standard COSC benchmarks. The movement provides the date complication displayed through the iconic Cyclops lens magnifier on the crystal, ensuring legibility at a glance — the functional heart of every Datejust since the reference's debut in 1945.
