Watch repairs

Borgel trench watch 24 9

Marvin 362, 29.5mm; bezel ⌀ 30.2mm. Bezel measured thrice: 30.17, 30.21, 30.24. So I went for a 30.4mm crystal and it was a success.

  • [x] Order 30.4mm crystal
  • [x] Polish silver
  • [x] Replace crystal
  • [ ] Rachet wheel is missing a tooth, still works but might replace from donor for completeness
  • [x] Pusher has come loose during cleaning -- fits in OK anyway
  • [ ] Service
  • [ ] Repair original strap -- see leather conditioner

Molnija 3602

Consolidating two pocket watches. After swapping various bits it seems both balances are wobbly. So perhaps a dirty balance bridge has broken the good balance? Might be a case of cleaning both and building a new one out of the best bits. See Ranfft and Linux Focus for movement details.

Rone Countryman

34mm manual, ~200° amplitude. Consolidate with a similar Rone with a date. Was originally just going to take the barrel from the second one, but now considering using the second with the date as the donee if it's looking OK after a clean.

Date version

Extremely dirty and smells of rabbits (apparently been in a loft). Appears to have been dipped in grease.

  • [x] Clean dial
  • [ ] Clean and service
  • [ ] Measure crystal
  • [ ] Replace crystal

No date version

Runs for a couple of hours but the mainspring appears to be broken. And it's not going back together nicely: train wheel feels scratchy when the bridge is tightened down.

  • [x] Polywatch
  • [x] New strap -- black Milanese bracelet
  • [ ] New cannon pinion -- evaporated during tear down
  • [ ] New mainspring -- suspect broken spring, slips after a few winds
  • [ ] New gasket
  • [ ] Service

Longines 12.92

Hands a little fragile, no case, 27.8mm movement, 26mm dial. I found a 16-jewel version with a wobbly balance to use as a donor, so basically I'll make one good one out of the two. Might've been easier to just to stick the good balance in the 16-jewel, but it seems both balances are a little wobbly. Will service and try again.
