Watchman Clock – Mechanical
Our first watchman model, Model 30, was developed by placing a key on the points to be checked on the guards' patrol route. When the guard arrives at these checkpoints, the key's entery time is written to the watch's report as soon as the fixed keys are in
the clock. It is possible to learn from the paper strip inside the clock about which points were checked and which check points are skipped. The model reached over 200,000 users and broke the all-time record.
