Appraising the perfection of a timepiece involve not only taking account of the complexity and the technical reliability of its movement, but also of its degree of finishing. After machining, the parts are rough and must be reworked by hand in order to ensure an impeccable appearance. The beveller (also known as a chamferer) handles part of this delicate stage in production. The artisan reveals each component by using his burin to accentuate its outline with a polished interior angle. He smoothes the sharp edges by removing any remaining burrs and rubbing them down. He polishes certain parts in order to better reflect the light. The result is not only luminous but also useful, in that polished and bevelled parts are more resistant over the long term and less vulnerable to corrosion.
