Hi you have the hole marked push located , there should be a tag visible which you push down to release the stem. Some time you need to pull out the stem before it is visible in the window so look closely in the hole and pull the stem so the hand set position and see if it appears.
@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.
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.
