History

The company was founded in 1912 by Walter Vogt in Granges. His philosophy was to overcome difficulties. In the 1920 and 1930’s, he took risk in taking part of the technical realization and marketing of John Harwood concept for automatic winding. Vogt tested different formulas such as rectangular and round water-resistant or sporty chronographs such as the “Fortissimo” or the “Wandfluh”. The company most exclusive product is an automatic chronograph with a mechanical alarm, designed by Zurich watchmaker Paul Geber on the basis of the popular Eta/Valjoux 7750.

Technical details

The watch comes with a Valjoux movement with caliber 7750 with 25 jewels, BHP 28,800 and 44 hours of power reserve. The movement was made around 1975.
