1905 Hans Wilsdorf
The history of Rolex is inextricably linked to the visionary spirit of Hans Wilsdorf, its founder. In 1905, at the age of 24, Hans Wilsdorf founded a company in London specializing in the distribution of timepieces. He began to dream of a watch worn on the wrist. Wristwatches were not very precise at the time, but Hans Wilsdorf foresaw that they could become not only elegant but also reliable. To convince the public of the reliability of his resolutely innovative timepieces, he equipped them with small, exact movements manufactured by a Swiss watchmaking company in Bienne.
