ETA 2879 balance cap jewel size?

[marcofilippin]

Hi folks. I was just finishing up an ETA 2879 rebuild and the balance cap jewel went pinging off into the wilderness. However the spring seems to be more elastor and not incabloc. Just wondering if anyone knows the size of the jewel I need to order. Also wondering where such data might be found online. Thanks!

Hi find attaced the KIF elastor document, It wont help in finding the lost cap but may prove useful.  First port of call in finding a replacement is Cousins uk watch parts  they have a function where you can make a request for unlisted parts, you may be luckey.

One of the things unhelpful with this watch is that with evolution it had different shock protection systems. Even a tech sheet is unhelpful but there is a cross reference guide and on page 5 of the PDF it looks like 516.
