In the control points are placed keys that when turning them print on the paper tape the exact time that the worker went through it.This type of watch was used to record a worker's route. They were used throughout the 20th century. There were fixed clocks, strategically placed so that the worker clocked in when passing through them, or mobile clocks like this example. In order for the company to have control over the worker, each time he passed through one of the specific points, he had to introduce the key located on it, which recorded the time he had arrived at that point. When the person in charge of checking the clock looked at the template with the hours marked, he knew perfectly well if the worker had been punctual in his work. These clocks were also locked, so that only the watch inspector had access to the paper template and it could not be manipulated by the workers.Authentic and original piece full of history!Measurements: 12 cm (box diameter).
