The Tissot Powermatic 80 is a Swiss Made self-winding automatic movement with 23 jewels. It is found in various Tissot models and is based off of the ETA caliber C07.111 watch movement. This caliber’s claim to fame is the high 80 hours power reserve.
There is confusion about whether or not the Powermatic 80 movement uses plastic parts (similar to the Swatch Sistem51). First, it’s important to acknowledge that there is more than one Powermatic 80 caliber. For example, The Tissot Luxury line has the Powermatic 80.111 with 23 jewels and uses plastic parts. The COSC rated Powermatic 80.811 found in the Tissot Ballade does not.
