I started out on pocket watches, but soon hit the smaller stuff (apologies to Mr. Dylan). I picked up a Citizen on eBay. It has a Miyota 8200.
Tore it down and left the balance hole jewels in place as I thought they were fixed (I did remove the cap jewels).
Ran the parts through an ultrasonic cleaning and checked to see that the balance bridge hole jewel was still there (it was, but I didn't look at the lower plate hole jewel) so I rinsed away the cleaning solution under running tap water. Sure enough, when I looked again one of the hole jewels was gone down the drain. The other was loose in the container and was retrieved. Lesson learned.
Anyway, I'm trying to find a source of these balance hole jewels. Any help would be greatly appreciated. Thank you, Muskie71

Hey Muskie! Welcome, and I feel your pain. I’ve lost plenty of stuff before now, usually to the carpet...
The tech sheet for the Citizen 8200 shows the balance lower jewel part number as 098.09 and the cap jewel as 094.04. Cousins UK have the cap jewels in stock but the ‘spiral spring with jewel’ is expected mid-March.

Firstly Welcome aboard the WristSushi Train !
So trying to land soft here and not be disrespectful with my first reply to a new member, but given a new Miyotoa 8200 movement costs around $40 USD why not just source a brand new one? Given the lost jewel and the efforts ahead of you it would be a reasonable way out of this conundrum.
Seiko 7S26 movements cost me $30 from Seiko USA parts department when they go bad I just get a new one and pop it in.

Hello leffemonster and thank you very much for the info on part numbers from Cousins!
And thank you for your question HiBeat. I agree with you buying a new movement would be less effort. I did think of buying an old beater on eBay and scavenging the part from it but I'd rather not. When I got into wrist watches I realized the fun and enjoyment, for me at least, was to look at the performance on a timegrapher then disassemble, clean, oil and re-assemble the movement and see the improvement on the timegrapher. I found this is true for old as well as new movements, so just popping in a new movement, one doesn't get the performance that the movement is capable of. I recently did this with a new NH35A and it's keeping remarkable time. Anyway, thanks for the welcome to the forum.
