Description
The ladies' watch form movement DuRoWe 89 was a typical representative of that
category, which was extremely popular in the 1960ies and 1970ies.
Noteworthy on this movement is, that minute wheel, third wheel and fourth wheel are arranged
on one line.
The rest of this movement is business as usual: Shock protected ring balance (beared in
inhouse Duro-Swing shock protections), pallet anchor escapement, hairspring with moveable stud,
regulation only directly on the hairspring key and one cap jewel for the escapement wheel.

shown here).
