Rolex Submariner

The Rolex Submariner is a line of sports watches designed for diving and manufactured by Rolex, resistant to water and corrosion. The first Submariner was introduced to the public in 1954 at the Basel Watch Fair. It was the first watch to be waterproof up to 100 metres (330 ft), although Blancpain's Fifty Fathoms watch, which was introduced in 1953, was certified to 94.5m (being fifty Fathoms). The Rolex Submariner is considered "a classic among wristwatches", manufactured by one of the world's most widely recognized luxury brands. Due to its huge popularity, there are many homage watches by well-established watchmakers, as well as illegal counterfeits. The Rolex Submariner is part of Rolex's Professional line. Today, the Submariner and Submariner Date models are equipped with Rolex Calibres 3230 and 3235, respectively, and feature luminescent hour markers, a unidirectional rotatable bezel with Cerachrom ceramic insert, and a solid-link Oyster bracelet. The models underwater diving depth rating is 300 metres (1,000 ft).
