Abstract
One aspect of the invention relates to a method for producing an opening in a glass or sapphire timepiece component, according to which, in a first step, a glass or sapphire blank is produced or supplied, in a second step, a geometry of the opening is defined and the opening is cut in the form of a hole or contour by a laser filamentation method, and in a third step, the timepiece component containing the opening is separated from the scrap resulting from the filamentation method by chemical etching. The invention further relates to a watch having a glass or sapphire timepiece component with at least one opening made using this method.
