DuRoWe 7422/2 (INT) / Dugena 2113


This one is one of the last movements, made by the german movement factory DuRoWe. The whole 742sx series compares will with contenporary swiss movements of the 1970ies. The 7422 bases on the caliber 7420/2 and extends it with an instant date mechanism.

This movement was sealed into watches of the “Dugena Safety” series, which were very rugged watches with thick steel cases and mineral crystals. Because of that, this movement was also known as “Dugena 2113”.
