Pantograph is a type of watch mechanism which uses a linkage system to transfer the force from the mainspring to the escapement. It is composed of two or more interconnected levers which move in unison when the mainspring is wound. Pantographs are used in many high end timepieces, and are known for their accuracy and reliability. The use of a pantograph in a watch increases the accuracy of the timekeeping, as the power of the mainspring is evenly distributed throughout the watch.
