Skeletonizing is the most expensive, ambitious and most traditional form of watches finishing. The watchmaker uses a scroll saw and countless files, some of which he makes himself. Here, the movement is reduced to a minimum of mechanical parts and thus freed from all unnecessary components. The supporting stuctures is all that remains. You can also skeletonize dials, gears, winding wheels and other parts.
