New battery and still not working???
There are no mystery at all. If you leave flat battery inside watch for a long period of time, battery may explode or leak. Leakage is happening most often and when it happens it is allmost invisible to naked eye.
However, the leaking solution consists of various chemical solutions and they react with metal, alloy, brass, led and other metal parts of which watch movement is made. This process is called ''oxidation'' and it works like rust on metal. You can see it wth a help of magnifier and it looks like tiny fungus layer all over various metal parts.This layer do not transmit electricity as well.
Sometimes it's possible to repair watch (depending on how much damage has been done), but in my experience few times I came across the situation that new movement replacement was needed.
All watch manufacturers are advising not to leave watches with flat battery in and if not changed for the new one ASAP, get the flat battery out of watch.
All you can do is to find your watch repair shop and ask what's possible to do. Speak to the watchmaker, not the jeweller.
Best of luck with your watch.
