Hans Wilsdorf was born in Kulmbach, Bavaria, on March 22, 1881.
1900, he settled at La Chaux-de-Fonds where he did clerical work for a watch exporter.
In 1903, he left to work in London. Soon after, in 1905, he founded a wholesale watch business, WILSDORF AND DAVIS, signing a contract in Bienne with AEGLER, to guarantee them distribution of watches under their name in England.
The name ROLEX (an abbreviation of the French phrase “horlogerie exquise”) dates from 1908. AEGLER watches were checked by the watch test service in Bienne, and their movements were double-checked at the Kew Observatory in England.
The Aegler company was renamed the ROLEX WATCH CO. AEGLER S.A. in 1914.
Wilsdorf transferred world exports to Bienne to thwart the British Government, who had imposed an import tax of 33.3% to finance the Great War.
He founded MONTRE ROLEX S.A. in Geneva in 1920.
The movements were made in Bienne. ROLEX assembly, testing and sales were in Geneva.
To improve the water resistance of wristwatches, Wilsdorf registered a patent for a case with
screw-down winding crown in 1926.
On 17 October 1927, the typist Mercedes Gleitze swam the English Channel in 15hrs. 15mins. wearing a ROLEX OYSTER.
In 1931, thanks to the talents of the technician Emil Borer, Wilsdorf presented an automatic permanent rotor winder, the ROLEX PERPETUAL. He retained the exclusive rights, and prohibited the automatic movement’s use by any competitor for the next fifteen years.
