In addition, the production technology of silicon allows watchmakers to make very complex parts with precision that cannot be matched by steel. With the flexibility of this component in the definition of geometry, it is possible to carve out a hollow structure with a smaller rotor and moment of inertia, allowing more energy to be transmitted to the balance. Finally, silicon can also be used to make one-piece parts, such as built-in pawl pallets, and the design itself improves accuracy.
