does the hairspring always need to be shaped where it rests against the regulator pin? Or is it ok if the hairspring touches the boot side with the screw slot instead?
Seems to me it wouldnt make a difference as long as it touches one side or the other
i recently broke my patek 5134 by winding a little too vigorously. heard a click sound and can no longer wind the watch.
it has a 215 PS movement
after dissasembly, i see that the "under" wheel that the crown wheel is attached to (located under the barrel bridge) has a couple of broken teeth.
the wheel has 3 screw holes and a nub in the middle for the crown wheel to attach to.
from my searches on the internet, it appears this part is #421, but i am not sure, wondering if anyone can confirm correct part number
or has any ideas where to procure part. i will attach a picture showing the part, its the silver part under the highlighted bushing with 3 holes in it.
Hopefully a decade of experience after graduation from Mark Lovicks courses, you will have acquired enough skills to attempt servicing the Wittnauer complications. Let us enjoy watching its picture please.
Meanwhile we can have fun playing baseball or with the seiko.
Just a thought.
