In 1981, Vianney graduated from a watchmaking school in Paris, France.  He established himself as an independent craftsman and worked for eight years in the horological field restoring ancient clocks and watches. 

In 1994, he founded his own company in Sainte-Croix in Switzerland under the name of Janvier SA and launched his first collection at the 1998 Basel Fair: Antiqua. 

Since 2000, Vianney Halter has been working together with the French Designer, Pascal Pagès, to imagine new watches.
