Adeodatus Posted April 10, 2012 Report Share Posted April 10, 2012 Need a bit of advice. I dropped my A2892 Spitfire the other day. It fell flat on the back, and miraculously there are no dings or dongs. No I'm noticing that it runs +5 mins a day, though. I tried to regulate, checked the hairspring and the bridges, but nothing. Today I noticed that it stopped working, so I opened it up again and the balance was sort of stuck. I gave it a nudge and the watch started ticking again. It definitely needs a repair, but I was thinking about doing it myself, if I will not need parts. In that light where would one look for issues in this case (watch dropping flat in its back), especially the least obvious places? Help me to help my poor patient, dear doctors...

Rolexman Posted April 10, 2012 Report Share Posted April 10, 2012 Look for a broken balance staff or dislocated balance cap jewel or spring. Link to comment Share on other sites More sharing options...
Adeodatus Posted April 10, 2012 Author Report Share Posted April 10, 2012 Look for a broken balance staff or dislocated balance cap jewel or spring. The balance is ok as far as I can see and the cap jewel is fine as well. Damn it.... I'm screwed... Link to comment Share on other sites More sharing options...
Rolexman Posted April 10, 2012 Report Share Posted April 10, 2012 Looking at it is not enough. You need to remove the balance and inspect the staff and upper and lower jewels for cracks or dislocation with a 10x loupe. Link to comment Share on other sites More sharing options...

There is no way you could tell any real damage to the jewels by just looking at it. You need to disassemble it and examine it under really good light and with a loupe. The crack could be barely visible, and yet that could cause some serious issues. Link to comment Share on other sites More sharing options...

Like a freaken mystery Ah ok, good job You could take a look at the regulator studs (the arms on the balance c ock) and the hair spring coils. Maybe one of the coils got tangled up or slipped out of the stud. 1 Link to comment Share on other sites More sharing options...
freddy333 Posted April 10, 2012 Report Share Posted April 10, 2012 I agree with the previous recommendations. You need to remove the balance & inspect it carefully. If the watch is running fast, most likely the hairspring is crimped or tangled on an adjacent wheel or bridge. Also, check to be sure the cap jewels (both upper & lower) have reset to their center/null positions in the shock assemblies. Link to comment Share on other sites More sharing options...
stiff muckler Posted April 11, 2012 Report Share Posted April 11, 2012 These are all great ideas. Per da thread title, da last place to look might be for da loose bridge or da bent pivot (and not necessarily on da balancier staff). sm iiH!

blazed7 Posted April 12, 2012 Report Share Posted April 12, 2012 Ditto the hairspring suggestion. Having suffered a hard shock and running fast sounds like it could be tangled. Link to comment Share on other sites More sharing options...
