This watch is unusual among swatches because, not only is it mechanical but the back is actually removable. I think Swatch do this only to the mechanicals.
Swatch started deviating away from it’s original concept of keeping it stupidly simple around 1990. The first automatic was seen in 1991. This model, the Mc Killop, the name is inspired by the tarten strap, is from 1995 and the timing is by the amazing ETA 2842. I see this movements and/or its varients in watches 20 times the price. It is signed three times including on the glass and I love that.
About the Swatch brand
The original swatch range was introduced in 1983 with two styles, a large and a small for women. They came in various colourful designs. They were not repairable; the case was an entire single unit. The only maintenance possible was a battery change and a strap change. At A$50, they where cheap, and were an instant success, possibly the greatest success of all time. During this period the biggest and proudest names in the game were one by one going to the wall, Swatch was there gobbling them up until Swatch controlled virtually the entire Swiss industry.
