The movement is running and the alarm is operational. The slide to the case side is winding the alarm train. The hour, minute, and alarm hands are set smoothly. There is tarnishing and oxidation on the plates. The dial is in good condition. The case has light marks and scratches, with the Lange marks slightly rubbed on the covers.
