The Heritage

The Sistem 51 was introduced by Swatch in 2013 as the first fully machine-assembled automatic mechanical movement. The Sistem51 caliber is composed of 51 components with date indication and a 90-hour power reserve. The case features standard Swatch dimensions with a construction that does not allow for traditional maintenance interventions.
