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.
You know, I wonder if I could adapt a micro-mesh single-serving reusable coffee filter to the same purpose. I keep ending up working on large (50 & + mm.) Swiss pocket watch movements that would not fit into smaller cleaning holders.
But they might fit in a coffee filter.
You gave me an idea, sir! Thank you.
Karl here. I would love to see pics if you can post them. I know very little about Seiko. But Wittnauer I've seen off and on. I know some repair technicians can charge a pretty penny, but did the estimate they gave you go into detail on what the needed repairs were. That figure does sound pretty steep. Was it dropped from a B52? (Which could actually cause a costly batch of repairs I imagine.) Either way, it would be a great thing to get it running. I wish you luck with them both.
