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.
The Oyster Precision was focused solely on time, while the Oysterdate featured a date function. The original Oysterdates were released with the dial reading "precision" instead of "Superlative Chronometer, Officially Certified." The Waterproof Oyster Case was considered thin for the time, opening the Rolex brand to a wider range of people.
Some of the most underrated Rolex watches bearing the name are the simple, snap-back dress watches dating from the 40s through to the 70s. Most of these watches were released in gold, with variations in case and dial design.
