Help needed in troubleshooting fault

[DozyGit]

Dear All,

In 2009 I bought an astroavia watch powered by a Miyota 0S80 movement. The battery ran out a while ago, and I got it replaced recently at a local jewellers. It was working well and that night the minute and hour hands were stationary at 11:15pm, but the second hand was ticking (in the small eye).

The minute and hour hand move when you set it, but not when working. All other things are working OK, I am at a loss to understand what might have gone wrong?

I took it back to the shop and they don't know and want to take it to another watch repairer.

I have a feeling they don't know what they are doing! Don't want to go on a wild goose chase for a £100 watch and thinking about fixing it myself, if possible?

Thanks a lot for your time and help
