Vintage Citizen Crystal King Seven


I recentely bought a vintage Citizen watch from the 70’s. It doesn’t run very accurate.

I was wondering what movement is in it and of it is stil available on the market.


I believe all Crystal Sevens ran 52xx movements. They were phased out in the late 70s as Citizen moved to 82xx movements for their entry-level automatics.

Parts are fairly easy to get though and any competent watchmaker should be able to regulate it to be more accurate for a nominal fee.
