David Seyffer: From written sources we know for example, that the watch with the Nr. 579 was made not at Baumgartenstrasse 15 (where IWC production has been located since March 1875) but at the first atelier F.A. Jones rented from Schaffhausen city, which was located some 500 yards away.
In those days, only a few watchmakers were manufacturing IWC watches. Jones still had to organize the company and find investors, but he also had to start making and selling watches. IWC in the times the watch No. 579 was made was a start-up business that had to face a lot of different challenges. Sources at the City Archives in Schaffhausen helped us understand that F.A. Jones at that time had a very well-organized supply chain. Movement parts that he could not yet manufacture in Schaffhausen were purchased in the western part of Switzerland. Step by step and year by year the percentage of inhouse production was raised.
It is important to understand that Jones did something completely different in Schaffhausen and therefore was a pioneer. He implemented the so-called American system of watchmaking in Switzerland for the first time while in the western part of Switzerland manufacturing was still carried out in a kind of cottage. The huge step towards a modern way of manufacturing watches was established in Switzerland after 1878, ten years after F.A. Jones founded the International Watch Company.
