The Mido 1127OC watch movement is a detached manual wind movement with an indirectly driven minute hand, allowing for a relatively large balance and low profile. It features a Type VS rotor, which is a single-part rotor that is 0.6mm higher. The movement includes several functions such as automatic winding, a digital display for seconds, minutes, and jumping hours, and a date function that can be quickly set by repeated pulling of the crown. The Mido 1127OC movement was commonly used around 1975.
