Seiko h357 keyless works help needed

[camrok]

I got this nice little h357 that should polish up nicely.

I have had to mess with the keyless works to sort out the analog set.
This is now sorted.
In doing so I may not have reset the digital fingers properly as I Can’t adjust the digital display.
It does flash but forward /back crown adjustment does nothing.

I’ve followed the technical manual but am not sure if something is not sitting correctly.

Here is a pic of the keyless.
You will have to zoom most likely.


I haven’t been able to see any videos or pics related to repair of these. And at my level the tech manual is a nightmare to figure alignment and what bit goes over and which bit goes under.

Any advice will be greatly appreciated.

Thanks
Cam

Have you stripped it completely?

I'm afraid that just cleaning the keyless work wont do it. My guess is that the I/O switch for the crown adjustment has oxidation (best to clean it gently with solvent, fiber glass pen or toothpick/peg wood).

Also you most likely to have to give a clean for the analog part as well as otherwise it'll run slower than digital number.

Also check the contact pin heights (I think the manual refers to this).

the I/O switch was the post suspicious piece when I was rebuilding the keyless in therms of placement too.
I’ll add better pics when I pull it down again.
Thanks

It's good to check the both circuit and switch arms. Use a loupe if you have one to see all the possible crud.
