Despite earlier attempts to house a finished wristwatch inside a second waterproof case, it wasn’t until 1926, when perfect replica Rolex released the Oyster, that such a watch became a reality for consumers. (To get technical, let’s say “highly water resistant.”) First displayed inside a fish tank in London’s famous Selfridges department store, the Oyster drew crowds of shocked people by keeping perfect time underwater. When Mercedes Gleitz swam The English Channel (or part of it) with an aaa quality fake Rolex Oyster on her wrist, the entirely dry watch made headlines as part of what is arguably the first “advertorial,” giving birth to the star adventurer as watch ambassador.

The Oyster had three innovative features that assured its waterproofness: a screwed-on case back, a crystal screwed into place with the threaded bezel, and a screw-down crown. Though luxury replica Rolex has since replaced the screwed-in bezel, the fluting of that early bezel remains an important aesthetic feature of modern Swiss movement fake Rolexes, especially the Datejust and Day-Date.

The basic scheme for waterproofing the case remains essential to modern dive super clone watches online from all brands, and the name “Oyster” remains essential in the high quality replica Rolex UK lexicon as indicative of a water-resistant case.
