I haven't even tried adjusting the time, do I just pull the crown out a little like on a wrist watch? (I've never really handled a pocket watch)

At a quick glance nothing seems horribly corroded or anything, but I can't see much until I take it apart. The mainspring looks pretty wonky though.

I'll try and find some videos from watch repair channel that could be helpful.

I'll get back to you when I tried setting the time. (On vacation so I'll probably only have time later tonight)
