This old Durowe movement is very reliable, and even hard abuse (you can see the rust) did not manage to break it. It runs today as strong, as it ran, when its watch was bought. Only the oscillating weight scratches on the back.
Many watches of the 1950ies were equipped with these “Duromat” movements, and this one even has got the old “Duro-Shock” shock protection mechanism.
