About the Swatch Sistem 51

The Swatch Sistem51 is an automatic watch whose mechanical movement is assembled entirely by machine. Swatch presented it at Baselworld 2013 as the first mechanical movement with fully automated assembly. The movement has 51 parts, anchored to a single central screw.

It is made in Switzerland on a 20-metre automated line in clean-room conditions, without human intervention, from ARCAP, an anti-magnetic alloy of copper, nickel and zinc. A bi-directional rotor runs around the edge of the movement, leaving the works visible through the caseback, and a full wind gives 90 hours of power reserve. There is no regulator to adjust: the rate is set by laser at the factory. The movement is sealed into the case with structural adhesive, so it cannot be serviced.

Plastic and steel Sistem51 models share a 42 mm case, about 13.8 mm thick, under an acrylic crystal, so what separates them is the case material and the dial. The plastic models include the Sistem Black (SUTB400), Sistem White (SUTW400) and Sistem Red (SUTR400), along with the Sistem Polka, Clouds and Arlequin.

In 2016 the movement moved into steel. Irony is Swatch's name for its steel-cased watches, and the Sistem51 Irony puts the same movement in a 316L stainless steel case, with more grown-up dials than the plastic models. The first of them were the Sistem Earth (YIS400), Soul, Arrow and Fly, the Sistem Boreal (YIS401G) on a steel bracelet and the two-tone Sistem Tux (YIS405G), with the Sistem Stalac as a steel model for women. Other steel models include the Sistem Khaki, Sand and Snow.
