Notes

Dial, case and movement signed. DIAM. 56 mm. Used by PIAGGIO in their factory, these timers were used to count the speed of assembly on the production line. Once the timer is started it does one tour every 5 seconds. The small counter indicates the amount of tours it has done. An interesting tool used at the HEIGHT of factory production lines.
