Jewel sizes question.

[Davey57]

I have lost a balance cap jewel stone from a movement, they jump like fleas, never to be seen again!  Anyway, I have a few scrappers that I have compared and tried to fit but, no go. I have found an assortment at Cousins,  https://www.cousinsuk.com/product/jewel-holes-end-stones. I have never had to find a replacement before and just wondered whether it’s likely that there will be one of the size I need amongst them or can you buy them by size somewhere? I’ve measured the other one and it’s 1.10mm.  

Thanks

Hi dave, Use a transparent bag, zip loc ... To remove and  install the end stone inside, check my thread titled ,   tips on safe removal and installation of fidly jewels.

Will you also disclose the caliber you lost the jewel off of. 

Regards

Hello Joe

I  will definitely have a look at you post. It’s a Forster 187. These are the only one I have come across so far that are clear, even harder to spot!

That’s great thank you. I’ve bought stuff from John before. I must confess I did look on his website but completely missed those!

Thanks to all.
