Hello everyone!

I am currently at a loss for a place to source jewels for a main plate I am currently working on. I've removed the jewel intact and was able to acquire the correct measurements using a JKA Feintaster micrometer. 

Outside diameter is 0.99 so jewel size would be 1.00 mm

Inside diameter is 0.12 mm (actual) so a 0.14 mm jewel is required. I measured the pivot associated with this measurement. 

I've tried the following: Cousins UK, Jules Borel, Otto Frei, Daves watch parts, Esslinger, and Twin City Supply.

 

Any sources would be appreciated. 

 

As always thanks in advance.

when replacing jewels it's nice to have a reference book like the link below. Then even look at the reference book and see what standard jewels are available so I've attached an image of a chart. You've indicated it's a plate jewel 14 x 100 or I guess technically to be 0.14 x 1.00 which I circled it's a standard plate jewel of a standard size.

okay so cousins have lots of jewels but of course as you may have found out we have a problem it's no longer available it's been discontinued. As watch repair moves more for well basically no parts being available parts will slowly disappear so your size has been discontinued but if you're willing to open the hole up a little bit you can have a 14 x 1 50. then of course the other thing to do is if you look in the book there's a way of closing a a hole although I don't know if you could drop it from 1 to 90 because that's available also

so if you're buying from cousins you would have to open up your hole to accommodate the bigger jewel or continue searching online and may be fine the link below. then I snipped out an image on the page below I believe that's what you're looking for plus you'll notice they have other sizes to and there on sale.

      Been there. Worn that Tshirt.  'ping'. Hands and knees. Nothing. Nada. 20 minutes? Ha! I found it 7 month later. How? Well, after advice from a member, I invested in a £4 UV light torch.  Hands and knees looking for a 'ping' from a Sekonda, found them both within 30 seconds. UV makes the jewel shine. easy peasy. Could have taken longer. Just lucky on the location of the search. Hope this helps.

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Without Our Forum

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross
