I want an autoquartz watch for my small collection, eg a Tissot PR200. Probably they use this ETA movement. Used ones on Ebay do not cost much, but usually require a new battery cell. But the position of the rechargable battery is SCARY. I am an amateur and really fear that this plate replacement above the battery compartment is really, REALLY delicate, as it removes gears as well. Just what were they thinking when designing this movement?? These cells do not run forever, lose capacity over time.
