The Rolex brand was founded in 1905 in London by Hans Wilsdorf. It is known for producing high-quality, reliable watches. Rolex watches have been used to break records and push boundaries, such as the first swim across the English Channel while wearing a Rolex watch. The company moved its headquarters to Geneva in 1910. Rolex employs over 6,000 people worldwide and sells around 750,000 watches per year. It is the top luxury watch brand in terms of sales.
