In the mid sixties, Citizen launched the medium-sized selfwindig caliber 6000. It contains a ball-beared rotor, which winds in both direction and a spring-less ratched mechanism. The large Glucycur balance is pivoted in the inhouse Parachoc protection system.
All gears are located under one single plate, which makes servicing works a little difficult.
The date changes slow over almost two hours, but it can be quickset in the middle crown position.
How rugged this movement is, can be seen on the traces and dirt on it. Nevertheless, the rotor winds as smooth, as on the first day and never touches the case or the plates.
