New Grooved Balance Staff

From American Horologist magazine, December 1938

New Grooved Balance Staff

Here you see Elgin's new grooved balance staff, incorporated in the new 15/0 Elgins. Note the groove in the staking shoulder just below the riveting rim. This groove eliminates the possibility of damage and distortion to the balance staff hole when staff is replaced.

The staff may be driven out with a staking tool without damage to the balance. No lathe work is required.
