In addition, the silicon manufacturing engineering that watchesmakers can generate incredibly intricate parts, and its precision is unmatched by steel. With this definition from the geometric elements of flexibility, could be carved out belonging to the rotor along with a scaled-down instant of inertia belonging to the hollow structure, to assure that much more vitality pass for the sense of balance wheel. Finally, using silicon could also be integrated to the type of produced parts, along the lines of embedded pawl escapement fork, however the style and design by itself can enhance accuracy.
