Guilloché lessons at the atelier of Jochen Benzinger

The guilloché lessons continue. A recent day was spent from early morning to late evening at the atelier of Jochen Benzinger, working on my guilloché skills.

The task was a practice dial. A brass blank is fixed onto the support; the small seconds is finished first with a sun guilloché, then the main dial, also in a sun pattern centred on the small seconds, which gives the dial a striking appearance.

My thanks go to Jochen Benzinger, Marc Jenni, Beat Haldimann, Svend Andersen, John and Stephen McGonigle and Markus Döttling for their support, and to my parents, without whom none of this would have been possible.
