Notes
1958-1963
flat freesprung hairspring
DuraBalance regulator: balance with two regulating weights, shifted simultaneously along the spiral-shaped spokes with a regulator lever
Elgin combined settings (similar to Kif Duofix) for the balance; shock protection is realized by the elastical balance spokes
indirectly driven minute leaves space for a big balance and a rugged rotor bearing
automatic with two roller freewheels stacked on the rotor hub
unusual: ratchet only in selfwinding gear, crown mechanism with rocker bar
