For your consideration, we are offering this vintage Detex Corporation Guardsman watchclock. This would be carried by a security guard as he made his rounds, using numbered keys mounted at specific locations in his AO. Each time a key was used it would imprint the key number on a strip of paper locked inside the watchclock, giving the supervisor a clear confirmation that the guard completed his rounds completely and on schedule. This piece is in fair condition, with the glass crystal missing, the leather case is worn with some spots being worn through, both face screws are missing, and the keyhole cover is not present. The original instructions are still in the leather case! this measures 6 1/2″ round by 2 1/2″ thick. There are no keys included.
