A Swatch Irony Automatic is similar to a plastic Swatch Automatic. In 1994 Swatch launched the first collection of stainless steel gent and medium size Ironies in the USA. It was an instant success.
The most important thing about an Automatic Swatch is the fact that it doesn't need a battery: the movement from your arms powers the mechanism.
There are two versions: with and without date. The case of these watches is made of stainless steel.
