This was launched again in 1967 (reference 1665), the Rolex ‘Double Purple’ and continues to be a mannequin title used right this moment. It was an evolution of Rolex’s famed dive watch, the Submariner. The Submariner at the moment had a depth ranking of 200m/660ft, nevertheless, the Sea-Dweller was aimed toward those that went deeper and had a depth ranking of 610m/2000ft!
Variations Between the Sea-Dweller and the Submariner
