I am not a fan of battery run movements unless they are 'different' (unique) or show progression in development. This electo-mechanical has an electronically controlled balance via a coil and a small circuit board. The rest is mechanical. It was a time when mechanical started to be replaced by electrical. Good runner. Swiss made.
