Rolex Datejust Oysterquartz 5100

Rolex Reference 5100, famously nicknamed the "Texano", stands as a historic milestone as the brand's very first quartz timepiece, following the joint Swiss development of the revolutionary Beta-21 quartz movement. This ultra-rare, limited-edition mode features a substantial, angular 40mm case made from solid 18k gold, designed specifically to fit the large physical footprint of the pioneering electronic movement inside. It is distinct for breaking away from the traditional Rolex Oyster structure with its multi-beveled, futuristic silhouette, an integrated solid-gold bracelet, and a classic fluted bezel framing its clean champagne dial.
