With those clocks repairs can only be done by qualified repair people using authentic parts and here there is only one place in the entire country so what I would have to do is take it to the nearest retailer (not far) and have them send it in for repair, or courier it to the repair place direct (only 10ml/16km away but they don't do drop-offs), so there would be no parts for me to keep. However, as I've bought the replacement clock, hopefully I wont need their services for a few years at least.
