The Reason
The Vaucher calibers present on the site are examples from a manufacturing structure that has the capabilities to produce virtually every component of a calibre, and provide these products tailored to its customers requirements from 10 examples until many thousands.
Vaucher has between 30-40 clients, including some of the most famous houses in the watch industry. During 2017 they produced over fifteen thousand calibers. Their capacity of production is thirty five thousand pieces per year.
Each caliber developed at Vaucher manufacture costs up to five million Swiss francs to develop and takes between three to five years depending on complexity.
