Watch winder and tester for self winding watches, automats.
Simple device for testing automatic watches. It allows the mount of 6 watches at once. The arms are rotating around their own axis and the axis of the motor. The device does 3 rotations in a minute (3RPM). After repair and encasement just mount the watch on one of the arms. This can be done 2 ways: you can either mount the case without the strap by mounting it on the curved ends with spring bars, or with straps.
