Stauffer & Co. / Stauffer, Son & Co. Stauffer, Fils & Cie.
Stauffer & Co. was founded around 1830 by Robert Stauffer in La Chaux-de-Fonds. His son Jules Stauffer opened a London branch together with Francis Claude around 1857; it was called Stauffer, Son & Co., and its purpose was the sale of Swiss watches in London. After Jules Stauffer died in 1884, Claude entered a partnership with Charles Nicolet, who had been in London since the 1870s; before coming to London, Nicolet had attended the watchmaking school in La Chaux-de-Fonds for three years. After the retirement of Francis Claude, Charles Nicolet took over management of the company in London and La Chaux-de-Fonds.
