Comments about the data

The U.S. Time Corporation (Timex) bought Laco-Durowe in 1959. After selling it to the Swiss Ebauche SA in 1965, only mechanical movements were continued. Consequently the Durowe 900 was only produced for a short periode around 1965.

Example, year: signature; shock device
ca. 1965: Timex, West Germany, 8 Jewels; Duro-Swing
