Thank you so much!Looks like an EB (Ebauches Bettlach) 8027 pin lever movement. According to Mikrolisk, Seawatch watches were manufactured by Bermi Watch.
Thank you, Hartmut!
This is perfect, Hartmut! I didn't know where to start, now I have some direction. I'll start with the with the basic technical constructions, this will indeed be fun. Thanks again!!! ;-)What do you want to know? If you are looking for examples of different watch movements, you could hardly do better than Roland Ranfft's page. For the cheaper versions, Christoph Lorenz also has quite a few:
bidfun-db Archiv: Uhrwerke
Das Metatechnische Kabinett - Uhrwerke
As for explanations of how a movement works, I know of nothing on the internet (though I'm sure there are heaps of sites) - I always got my knowledge in that department out of books. If you want to scour the world wide wait yourself, try Auntie Google plus some of the following terms for the technical construction:
Swiss Lever Escapement
Pin Lever Escapement
Column Wheel vs. Cam [or Lever] System (in Chronographs)
...plus perhaps these for what's important in watches:
Knocking the Banking (this is actually something to avoid!)
Deviation in Daily Rate
Chronometre (SOCS) Testing
...and probably many more. Have fun!
