The term "Precision" on Rolex dials refers to watches that are not certified by the Contrôle Officiel Suisse des Chronomètres (COSC). These Precision labeled watches were introduced by Rolex to offer a lower priced product while protecting their main product lines. The first style was simple dress watches, often in gold or steel, first introduced in the 1940s. The second style debuted in the classic Rolex Oyster case in 1953, featuring the Oysterdate and Oyster Precision models.
During an era when Rolex was focusing on advancing their utilitarian, tool-based watches, some of their dress timepieces went relatively unnoticed. The Precision line, known for its simplicity, features classic designs that continue to impress.
