Rolex SubmarinerIn 1953, Rolex introduced one of the world’s first wrist watches geared specifically towards divers: the Submariner. Rolex had to confront a number of challenges when designing its first dive watch. The watch obviously had to withstand significant amounts of pressure and had to accurately measure time spent underwater, which the first Submariner achieved by featuring a 330ft/100m depth rating and a rotating diving bezel. It also had to be easily legible in conditions of reduced visibility yet aesthetically pleasing. Hence, the Sub’s iconic large white hour markers and Mercedes hands set against a contrasting black dial. The Submariner is the most iconic and desirable luxury watch of all time and has been adopted by luminaries such as Jacques Cousteau, Che Guevara, and none other than James Bond. Our favorite Bond, Sean Connery, wore a Big Crown Sub (early reference of the Submariner with a big crown and without crown guards) in the 1962 classic ‘Dr. No’. The watch was also featured in ‘Goldfinger’ and ‘Thunderball’.Reference 5513The Submariner reference 5513 was produced from 1962 to 1989. This model features crown guards, which were made to protect the Oyster crown. The pointed crown guards made their first appearance on the 5513 and were not much later replaced by the rounded crown guards. The base calibre for the 5513 is the 1530, which is not chronometer certified and therefore the dial bears just 2 lines of text instead of 4 lines, which is the case for Superlative Chronometer Officially Certified watches.
