Pantograph. Geneva,1857

An instrument for copying designs on an identical, reduced or enlarged scale.

In 1841, Georges-Auguste Leschot began working with a pantograph at Vacheron Constantin. It used a matrix or pattern to punch-mark and mill identical watch plates. This technique was the first step towards interchangeable movement parts.
