Does anybody know where to find jewels large enough for the upper plates in the early Walthams?

By my measurement they need to .134 diameter with the pivot hole being .015.

Thanks in advance!

Hi I have some envelopes marked plate jewels 15/130.
These are Seitz.
Is this the size you are looking for?

I think that might work. Are they clear? We have some that are 132 that fit decent but the center is way to small. I am sure 15/130 would be acceptable.

You can email us direct at mountaingoatz@hotmail.com if you want and let us know how many and how much. I check the email frequently through the day.

Robert, the .134 diameter you are referring to I believe is in inches. A Seitz jewel marked 15/130 is 1.30mm (so 0.0515") in diameter and will be much too small.

Mine are definitely in mm.
