In 1953, during the early days of scuba diving, replica Rolex for sale created one of the archetypal divers’ watch: the Oyster Perpetual Submariner, waterproof to a depth of 100 metres. The Submariner’s waterproofness was doubled to 200 metres in 1954, offering a comfortable safety margin for those diving with air, who rarely descended beyond the 60-metre limit. The watch’s performance and reliability soon put it on the wrists of elite divers, with whom Rolex worked closely to continually improve its watches.
In 1962, after the record-breaking dive to a depth of 313 metres in California, it became obvious that a new replica Rolex watches generation of divers’ watches was required, one that would be able to resist the pressure at depths below 200 metres. Rolex – having fixed an experimental watch to the bathyscaphe Trieste and successfully sent it almost 11,000 metres down to the deepest part of the ocean in 1960 – had the technology at its disposal to increase the Submariner’s performance.
In 1966, Comex made the first industrial dive to a depth of 160 metres. The French company developed a technique for saturation diving comparable to the idea behind the underwater housing projects, with the difference that the hyperbaric chambers were installed on ships that could sail on missions anywhere around the world. Saturation divers are taken down to working depth in the sea in pressurized diving bells and they return to the warm and dry pressurized chamber on board the support boat by the same method after their dive. Final decompression takes place only at the very end of their tour of duty. Comex, which came to be considered the leader in the field of commercial deep-sea diving, aimed to send its divers to 300 metres by the end of the decade. Rolex decided to make its next divers’ watch waterproof to a depth of 2,000 feet (610 metres). But in addition to increasing its resistance to external water pressure, thereby allowing the fake Rolex watches for men to descend deeper, feedback from saturation divers had uncovered a hitherto unsuspected requirement: the need to enhance the watch’s ability to withstand excess internal pressure.
Developed in 1967, waterproof to a depth of 610 metres (2,000 feet) initially and then to 1,220 metres (4,000 feet) in 1978, the Replica Rolex Sea Dweller was and is one of the watches for the real pioneers of the deep.
This is what the new Rolex Oyster Perpetual Sea-Dweller 4000 distinguishes it from the “old” version…
