Is there some-one who can give me the dimensions of the balance jewels used in a 16s 992B.
I know that they should be 0.011 pivot size?

What should the major OD be?
What should the minor OD be?
What should the overall thickness be?
What should the lesser thickness be?

I have several packets marked with WALTHAM 16s hole 11, but I am not sure if they are for 992B or not.
Do all the Waltham 16s balance jewels have the same dimensions?
Any help would be appreciated.

Mel I think the 992B is Hamilton.

Of course how foolish!
