The Kienzle 57/19 watch movement, used from 1966 onwards, features an automatic mechanism with a sub-second function. It incorporates a rather large balance and includes a ball-bearing rotor with a peripheral gear situated off center. It is usually equipped with 5 ruby balls. The movement also includes a ratchet on the dial side and a crown mechanism with a rocker bar. Additionally, it has a date function that can be adjusted by changing the 21-24 hour setting.
