WS 22: Servicing a SEIKO 7005 including replacing the balance

The watch has never stopped running, I have worn it for a day and kept it wound by swaying it. It is ticking happily. Thus I am very happy that my first solo service attempt was successful. It is a lot easier to work aside a tutor that will always immediately know what to do. And of course, I had a great support for this work with the great page of Rob describing his repair of the same movement.

I am planning to check the isochronisms of the watch on a timing machine later. Right now (lack of a timing machine in my work shop) I have manually or optically aligned the balance wheel by moving the spring stud to an approximate position.

Thank you for reading so far!

Best regards
