RolexSubmariner

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). The Submariner model went into production in 1953 and was showcased at the Basel Watch Fair in 1954. This first Submariner's assigned case reference number was either 6204 or 6205. It is unclear which model came first; in any event, the two watches are nearly identical. Neither had the distinctive "cathedral" or "Mercedes" hands later so strongly associated with the Submariner line. Rather, both of these early submariners have straight "pencil" style hands. The upside-down triangle at 12 o’clock; baton-shaped markers at 3, 6 and 9 o’clock; and dot markers for the remaining hours on the dail were design elements found in all later Submariner and other Rolex diving watch models. Both the 6204 and 6205 were fitted with the A260 movement and the watch cases had a diameter of 37.0 mm (1.46 in). Neither model displayed a depth rating on the dial. The 6204 was originally rated to a depth of 100 meters (330 feet), but by 1954, Rolex certified the watch as
