When a mechanical watch takes shape in the hands of a Swiss artisan, 164 micro-components collaborate like a symphony orchestra. The core tolerance of the balance spring system measures a mere 0.001mm – thinner than a strand of human hair. Our 3D laser alignment technology guarantees the 52-degree angle between the escape wheel and jewel bearings remains constant, unlocking the secret of high-end movements with ≤2 seconds daily variation.
