Rolex Oyster Perpetual 6509

The Rolex Oyster Perpetual ref. 6509 is a mid-century ladies’ automatic model, distinguished by its combination of elegant design and technical performance. Introduced in the mid-1950s, the 6509 was typically crafted in 18k gold or stainless steel with a case diameter of approximately 25mm. It was powered by the Rolex Caliber 1130, a reliable automatic movement designed to fit smaller cases while offering strong performance and a power reserve of around 42 hours. The design incorporated classic elements such as fluted or polished bezels, domed acrylic crystals, and refined dials available in silver, champagne, or pearl tones with applied hour markers and dauphine hands. Despite its small size, the watch maintained full Oyster functionality with a screw-down crown and caseback, ensuring water resistance. Its lug-to-lug measurement was around 33mm, with a lug width of 13mm. The 6509 was often paired with leather straps or matching gold or steel bracelets, appealing to women seeking both luxury and mechanical reliability. Today, the reference 6509 is appreciated for its delicate proportions, period styling, and its role in establishing Rolex’s reputation for high-quality ladies’ timepieces.
