A rare and charming piece of Rolex history. This Lady Zephyr ref. 6621 is the ladies’ version of Rolex’s celebrated mid-century Zephyr design, and it is seldom seen on the market today.

The 24mm stainless steel Oyster case is topped by the signature Zephyr gold bezel, an engine-turned design with notched hour points unique to this model. The silver sunburst dial features the distinctive crosshair pattern that quarters the face, accented by applied gold dot markers and elegant gold dauphine hands. The “SWISS” only dial marking is a hallmark of early-1960s production.

Inside is Rolex’s self-winding Oyster Perpetual automatic movement, proven for its reliability and longevity. It’s a refined, understated watch with genuine collector appeal and a style that still feels fresh more than 60 years later.
