In 1945, the popular fake Rolex Datejust watches come out. In 1950, Cyclops got the patent that was designed to magnify the date windows, making the date easy to read. In 1953, Rolex Datejust watches with Cyclops launched.
“Cyclops” is named after a colossus who lives in Sicily from Greek mythology. The “Cyclops” likes the eyes of the colossus, helping you read the date clearly and easily. Since 1953, Cyclops was widely used in Datejust, Day-Date and GMT-Master, which become the typical symbol of the hot copy Rolex watches.
However, for a long time, Rolex Sea-Dweller hasn’t apply Cyclops because of the large radian of sapphire glass (in order to guarantee deep water resistance). The first Sea-Dweller was launched in 1967. Until 2017, the black dials replica Rolex Sea-Dweller 126600 watches apply the Cyclops. Someone disapprove the change. They think that with Cyclops, Sea-Dweller is no longer traditional version. However, someone approve the improvement. I also agree with that, making Sea-Dweller better.
