Comments about the data

chronometer quality
flat freesprung hairspring
stud carrier regulator with friction gear
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

760: 30 jewels, 6 Adj.
761: 27 jewels, Adj'd

Example, year: signature; shock device
ca. 1960: Elgin, U.S.A, 6 Adj, 30 Jewels
