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
PART 3 of 3
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.
Thank you for the answers!
The bottom one yes and appears clean, i have oiled properly it now. Not the top one because I would need to remove the balance wheel to unscrew from bottom, the regulator is not boot type, I am afraid I will never mount it again, it's too tiny piece for my skills.
All these tests are passing fine, in my opinion.
I made a round of cleaning in ultrasonic for balance wheel and bridge, trying to better oiling, I will see if any change tomorrow.
No shim originally found... I will eventually consider one or two hour wheel shim/spacers eventually, if that woudl still make a difference.
Thanks again! I'll try to make good use of your suggestions, this movement means a lot to me.
Have a Sternkreuz press i use for most glasses. Love it. I bought a second one on tradera some month ago for spares. Also have an other which looks like a Robur but not 100% sure it's a Robur. Was thinking i could make an adapter so i could use some other dies as the Robur ones cost a lot of money. Maybe i can part with that as i have to many presses anyway.
