Some help with this Universal Geneve

Hello,
i've found this watch some days ago and started to search some information about it. But there's a little problem. I can't find pretty much!
And then I found this forum and hopefully you can help me in some ways. I will post you some pictures but I can't give you one of the mechanism because I'm scared of damaging the watch. Sorry for my bad english but it's not my motherlanguage. I hope you guys will understand it nevertheless.
