As one of the 100 most recognized and powerful brands in the world, Rolex designs, develops and produces in-house all the essential components of its watches, from the casting of gold alloys to the assembly and final finishes of the watches’ movement. The brand not only created the world’s first water proof watch, calling it the Oyster, but it also introduced one of the first self-winding watches, the Rolex Perpetual. Today, athletes such as Phil Mickelson, Roger Federer, and Lindsay Vonn are proud Rolex ambassadors, often spotted wearing their Rolex watches.
