I was nearing the end of servicing this seiko movement when I discovered that when the pallet fork bridge was very loosely screwed down, the pallet fork received power and snapped back and forth as it should, but when fully screwed down the pallet fork was squeezed too tightly and became sluggish. I read online that these jewels are usually friction fit and that I could push the jewel slightly further up to relieve the pressure on the pallet fork. I don't have the proper tool to do this so I fashioned my own, which was a poor choice. The jewel shattered of course, and now I need to figure out how to replace it and which of the hundreds of kinds of watch jewels available online is the correct one to get. Any help with this is greatly appreciated. Thanks!
Replacing jewels on a pocket watch
Extractor posted a topic in Watch Repairs Help & AdviceMy steep learning curve may about to become steeper still. As my first project I am working on a 17 jewel, Cyma 999 movement for which the replacement mainspring is now ordered. On closer inspection I can see that some of these 17 jewels are totally knackered so have been reading up on jeweling tools. On eBay the majority of interesting jeweling and staking sets are in the US. What is the most cost effective way to get myself kitted out? I have seen references to combined staking and jeweling tools but looking on the Cousins site they are two different tools. Is a Chinese imitation of a Horia like this any good: https://www.ebay.co.uk/itm/Horia-Clone-Watchmakers-Micrometric-Jewelling-Tool-Set-4mm-4mm-Multiple-Colors/303690725547?hash=item46b560b8ab:g:~LUAAOSwG-dfXw~Y Many thanks.
Just uploaded a new video. This one is one of my favourites, an Omega Military watch from the mid to late 40s. It had a broken balance staff, impulse jewel and the pivot on the centre wheel had a groove worn into it. I didn't film the lathe work but managed to get quite a bit under the camera. I hope it's useful to someone. Some pics:
