The Mido 916 watch movement was produced between 1956-1958, with 3210 units manufactured during this period. It featured an optional Reed's regulator and employed a noch friction controlled winding system. This mechanism included a differential gear between the barrel and barrel arbor, which prevented the rotor from moving if the mainspring was fully wound. The movement offered a sweep second function, along with an automatic feature. Additionally, it had a power reserve display of 44 hours.
