Rolex Oyster Perpetual 6507

The Rolex Oyster Perpetual ref. 6507 is a refined mid-century ladies’ automatic model, representing Rolex’s commitment to delivering high-performance timepieces in smaller formats. Introduced in the mid-1950s, the 6507 was typically available in 18k gold or stainless steel, with a 25mm case size that housed a robust automatic movement while maintaining elegant proportions. It was powered by the Rolex Caliber 1130, a compact self-winding movement designed for smaller case sizes, delivering a reliable 42-hour power reserve and smooth bi-directional winding. The design of the 6507 remained classic and understated, with a variety of dial finishes including silver, champagne, or white, often adorned with applied baton markers and dauphine hands under a domed acrylic crystal. The lug-to-lug measurement was approximately 33mm, and the lug width was 13mm, offering a balanced, discreet wrist presence. The 6507 also featured a fluted, polished, or occasionally engine-turned bezel, contributing to its versatile appearance suitable for both casual and formal wear. Today, the ref. 6507 is a notable collector’s piece among vintage Rolex women’s watches, prized for its mechanical quality, timeless styling, and representation of Rolex’s pursuit of excellence across all case sizes.
