There's a more detailed essay here

 

Thanks for the read!

 

hey golfer. That's definitely not the way to get started here ..... The experts here will only give their time to people who at least TRY and put a little effort in on their own.

 

Nevertheless an interesting subject. Below is a picture of my 167.0021 from 1971, which holds a cal. 712.
This model was issued in 1967.

 

Do you have details on the movement? OP only wants details.

 

Nope. The OP will have to satisfy himself with the links you provided
