Schlenker-Grusen GmbH ISGUS Night Watchman Control Brass Clock in good working condition. A couple of thoughts, the manufacture involved in this clock is of a very high manufacturing standard and the original manufacturing company, to this day, is still alive and doing well, in our opinion it is a museum piece. The brass case is in great shape, it is missing the lock key, the "watchman" key and any time printed original paper, top cover is open and, since the original opening key is not available, clock will be sent with the cover open, once closed it is not easy to have it opened, it has tiny scratches all around. The original movement in this clock is a clean and working well, we have not checked accuracy, may need a service. The winding key seen at photographs is included on the sale. Movement and case serial numbers are clearly seen at photographs and all match. Diameter is 88 mm at widest point circular case wise, 135 mm with chain holder extended and 43 mm thick.
