A vintage Simplex watchman's clock from West Germany is a fascinating piece of industrial history. These clocks were essential security devices in workplaces, factories, and other facilities, particularly for night watchmen or security guards. Their primary purpose was to ensure that guards were making their rounds and visiting designated checkpoints at specific times. Simplex was a major player in the time-recording device market, with its origins tracing back to 1894 when Edward G. Watkins patented the "Simplex" time clock. This clock comes with its original keys. Cased in an aluminum case and solid brass accents. Dimensions: Total height with knob 13cm.
