The well-known Submariner was launched in 1953, which is one of the most representative models of Rolex. But do you know when was the perfect Rolex Sea-Dweller replica watch released?

In 1960s, Rolex started a series of experiments to develop the timepiece that can explore the area under deep sea. Although the Submariner Ref.5513 was already water resistant to the depth of 200 meters, Rolex was not satisfied. After a series of experiments and research, Rolex cooperated with COMEX to create the helium escape valve, realizing the possibility of deep sea watches.

In 1960, Rolex cooperated with submarine explorer by fastening the Oystersteel case copy Rolex Deepsea Special on the submarine, refreshing the record of 1080 meters, 3,150 meters, 3,700 meters, 7,300 meters and 10,916 meters.
