Hello.
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.
This account is verified. WatchCrunch has confirmed that this account is the authentic presence for this person or brand.
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.
