Mido Caliber 80 (ETA C07.621 base)

Mido's 80-hour power reserve caliber based on the ETA C07.621, an evolution of the ubiquitous 2824-2 platform with a lowered 21,600 vph beat rate and longer mainspring. The Nivachoc shock protection and Nivaflex mainspring are standard ETA components. This caliber brought 80-hour reserves to the sub-$500 price bracket, making it a benchmark for value in Swiss automatics.
