Je cite Helmut Sinn
"About GUINAND: This Swiss company was founded in 1865 by the Guinand brothers in Les Brenets in the Jura Mountains, and has been under my ownership since 1996. GUINAND came to be known through the production of the first chronographs and split seconds chronographs. I have worked together with Guinand since 1953, when they started producing all Sinn watches up until 1994. GUINAND was well-known for its complication-watches and produced watches for many reputable watch companies in Switzerland.
Marque rachetée par SINN en 1996.
