What you see are the two versions of the very first Rolex Oyster replica watches sale, in other words, the world's first water-resistant timepiece. It was proven on the wrist of a swimmer, and when it was released in 1926 it was a rather big deal. The origin of the Oyster name is rather straightforward, borrowed from the sea-dwelling replica watches sale mollusk of the same name, and has been a hallmark of Rolex ever since. In fact, all Rolex watches produced today are technically in the Rolex Oyster collection (except the less common Cellini Prince models), sharing the first Rolex Oyster replica watches sale's focus on durability and water resistance. Rolex was a young brand when the original Rolex Oyster replica watches sale was released, but it was not until later in Rolex's history did the brand focus on the Rolex Oyster swiss replica watches concept almost exclusively. Hans Wilsdorf, German born and living in London, entered the watch industry in 1905 doing timepiece distribution in Britain and the British Empire.
