The Swatch brand was founded 1983 by ETA CEO Thomke and his Engineers. ETA is a watch movement manufacturer.

Speaking of Swatch and mechanical watches: the Sistem51 is an interesting watch, since it's the only mechanical watch ever fabricated in a 100% automated production line. The parts are welded together and held by a single screw. https://www.swatch.com/en-us/sistem-51.html
