Balance with Hairspring

A balance with hairspring is a key regulating assembly in a mechanical watch movement. The balance wheel and hairspring work together to control the rhythm of the movement, directly affecting accuracy and stability. These assemblies are often used in repairs when the original balance, hairspring, or pivots are damaged, worn, magnetized, or no longer performing correctly.
