Elgin Announces Their New Beryl-X-Balances

From American Horologist magazine, December 1938

Elgin Announces Their New Beryl-X-Balances
Rust-Proof... Truly Non-Magnetic... With the Same Hardness Which Has Made Previous Elgin Balances Famous

The BERYL-X solid balance is made from a heat treated hardened alloy, which combines the characteristics of resistance to distortion, stiffness, and wear resistance that are required of a balance. 

Where an ELGINIUM hairspring and a BERYL-X balance are used together, either part may be replaced without altering the temperature adjustment of the watch. Magnetism has no effect. Neither ELGINIUM nor BERYL-X will rust.

The above photographic reproductions, enlarged fifty times actual size, show the staff holes of BERYL-X, nickel, and staffs have been removed. In these photographs, compare the condition of the staff holes after the balance staff has been driven out with a staking tool. Note how the BERYL-X balance is superior to the nickel balance and equal to the compensation steel balance in distortion resistance, stiffness, and ability to withstand staff replacements. And remember - a poised BERYL-X balance will remain permanently poised, while a poised compensating steel balance can be disturbed by handling.
