“I started life as a watchmaker in 1948. Hartwig started out as an engineer. We work together well because he essentially does the design and engineering work that I can’t do. But I’ve had a lot of experience doing restoration of antique watches for museums. These are 200 to 300 year-old timepieces. We have both ends of the technical spectrum covered, from current engineering to an understanding of watchmaking 500 years ago.”
