Swatch Originals Sistem Class Automatic SUTS402 Unisex WatchSwatch Originals Sistem Class Automatic SUTS402 Unisex Watch The Swatch Sistem51 is a return of the 1983 Swatch to 2017; this time with a new movement. The basic concept of a Swiss made plastic watch still prevails, but developed in house this time, with an automatic movement constructed out of 51 parts. It is every bit Swatch, but a better Swatch this time. Exotic too, for not another plastic watch comes with a mechanical movement.
