Sinn watch stopped winding.

[Gingerbread Man]

Sinn 556 has stopped winding. With the see through back, It looks like it's engaging from the winder to an internal cog, but then I can't see any more of the process.

Is it a specialist job or an easy job for the local watch chaps? Any guarantee with these, not that old. I'll dig out the paperwork once home.

Thanks

I bought it late 2008. So no guarantee anymore. Had it a lot longer than I thought!
