The Alpina 634 watch movement is a mechanical movement that is characterized by its pin-lever escapement. It features a ratchet on the dial side and a crown mechanism with a rocker bar. There is a possibility of a cooperation with Kienzle, as the movements of the Kienzle 48 family are very similar. This watch movement is manual wind and includes a sweep second function. It was primarily used during the period from 1950 onwards.
