The Rolex Submariner has probably seen more variations and undergone more rigorous testing than any other Rolex model in history. Designed specifically for diving and underwater exploration, the popular watch has been featured in James Bond movies, adapted for military use, and continues to be loved and collected by many. Officially launched in 1954's Basel Spring Watch Fair (model number 6204), the Submariner remains a strong contender in the luxury sports watch market. It is clearly Rolex's most successful model ever. The modern Rolex Sub comes in a variety of styles (like the Hulk Submariner) and is fitted with a patented Cerachrom (ceramic) bezel, a Triplock winding crown, blue luminescent markers and hands, and is rated waterproof to 1,000 feet (meters). Even though it was originally designed for underwater use, its classic nature allows it to frequent the wrists of more “formal” species like successful businessmen and Wall Street bankers.
