What it is

The Powermatic 80 is based on the ETA C07, a derivative of the classic ETA 2824-2. To reach about 80 hours of power reserve, the Swatch Group lowered the beat rate from 28,800 to 21,600 per hour and lengthened the mainspring. The result is a Swiss automatic that is still running after a weekend on the bedside table, which is rare under €1,000.

Each brand gives it its own name. Tissot and Certina call it Powermatic 80 with a version number, Hamilton calls it H-10 (H-30 with day and date) and Mido «Caliber 80». The latest versions have a silicon or Nivachron hairspring, less sensitive to the magnetism of phones and laptops.

Its weak point is servicing: some escapement parts are synthetic and the group does not sell them to independent watchmakers, so servicing usually goes through the official service centre.

For anyone who wants an everyday Swiss watch with plenty of reserve and does not mind servicing it through the brand.

Maker: ETA, Swatch Group. The figures on this page come from each watch’s spec sheet.
