@aac58 I have read many times on this forum that soaking for several minutes in isopropyl alcohol does not dissolve or soften shellac to a noticeable degree. Have you had direct experience of shellac being affected by rinsing in it?

Would you suggest as a rinse in something else after cleaning in lighter fluid, or a different cleaning solution altogether? I used One-Dip on the balance, but lighter fluid on the cap jewels and settings. The faces of the cap jewels I polished on cigarette paper, but if the lighter fluid has left a residue, it is still on the hole jewels. I did not remove and clean the 3rd and escape wheel shock assemblies. I was advised not to, but as long as it's not an order of magnitude trickier than the balance shocks, I would be prepared to have a go.

Thanks for reply, but I didnt understand which part exactly should I push,black hole with pin just like remove sim from iphone?

Hi Longline   The movement you have in the photo is a shiojiri, owned  by epson seiko  I believe Perrins/esslinger in Canada and America have complete movements. Shiojiri Y573A        Vacheron_nl on the ebay has movement at $10.99.. he seems to have quite a bit of shiojiri and   epson ,
