Installing balance complete on Seiko 7s26 automatic.

Hello dear watchmakers.

I am having a trouble with a Seiko 7s26 automatic movement.

I happened to remove the balance wheel and the hairspring from the balance cock but

I have no idea how to refit them back.

I am afraid I might bend the hairspring.

I am used to balance cock with screws that hold hairspring but I need help on this..

Any tip would be grateful!

Hi  There are several videos by Mark our host on the subject and the technique involved during his overhaul/repair videos, my suggestion is to have a look and study his method.  There may be others By Jon who also adds videos and HSL another walk through contributer all excellent studs material.

Hello.

Thank your for your advice.

I searched the web for videos and couldn't find one working on Seikos.

Could you leave me a link of video that may help me??

Thank you:)

"How to refit (Seiko) Etachron" - often asked, you should use the search function. There is a section with pictures in the attached document.
