ERRORS IN THIS VIDEO:
At 3:42 you may notice I have placed the Intermediate calendar setting pinion reversed. If you are following this video whilst rebuilding your 7S26 then please take note of this.
At 4:55 you will see that the Intermediate pinion is now placed correctly.
Even experienced watch repairers make mistakes sometimes :)

In this video I am stripping down and servicing a Seiko 7S26 skx (Seiko 5) automatic watch movement which has not been serviced for a very long time.
