Like ro63rto says, I also thought all these small watch batteries are 1.5v, so extremely unlikely anything has been burnt out, it could be a small bit of debris blocking the train, if that is the case then cleaning the movement would be the only cure. If you have a Pound shop near you then you can buy a card of 20 or so small batteries for a £1, you can try different ones till you find the correct size. If it still does not work with a new battery try setting the hands and altering the time by several hours, this might free the train if you are lucky. Also try pulling the stem in and out several times, the reason being that pulling the stem out operates a small switch which stops the movement, if there is a bad contact then operating the hand setting stem several times just might fix it.

Odd - perhaps it was just a coincidence - the replacement battery failed at the same time as the movement failed. Any cracks in the circuitry?

I've never heard of a movement being "burned out" by a wrong battery - in most cases they just don't start up again - but others here may know better. It's possible that the battery leaked?

Hi Robert, here's my take on it. The plate that holds the minute wheel in place would appear to be the key to this. The captive minute hand will prevent the cannon assembly falling forward, so when the hour wheel is in place and the minute hand is fitted, it will keep the whole lot together.
