What american made pocket watches have friction fit balance staffs?

Hamilton 992B
Some Waltham 16sz

To add to Gene's good info also the later Howard Keystone Series 11 Chronometers.

Cheers

Here are a few more:
Hampden 12s Paul Revere
some Hamilton 10s
some Howard 16s, 12s, 10s

These came from "American Balance Staff Dimensions" - a list that I use a lot.

Welcome Gene.
Henry b. Fried page 100 of " Watch Repairer's Manual" has a list.
Fried book

Hey Douglas,

Is that list available at a web link? The only thing I could find that is close and available is a book available through CasKer

Waltham Model 1894, 1908 and on . . .
