as it adds precision to the entire construction. As Philipe Dufour said to me last year, the handfinishing adds to the soul of a watch. CAD, CNC and Spark Erosion are not proprietary techniques for the Swiss watch industry (or for the watch industry at all), therefore the question where these facilities are located ("in-house" or not) is not that impoartant to him. It is important to make a point with the handwork. Best, Magnus
