Made in Glashütte: 7.5. Classifying the balance spring and balance wheel

For a mechanical watch to keep accurate time, the balance—consisting of the balance wheel and balance spring—must oscillate at a precise frequency. The elasticity of the spring and the moment of inertia of the balance wheel are decisive factors here. Both values together determine the frequency. But which balance spring fits with which balance wheel? At NOMOS Glashütte, exact measurements are taken. These measurements are then used to decide which balance springs and balance wheels should be paired up. Other couples at NOMOS Glashütte meet more organically—the head of the NOMOS research department and his wife, for example.
