The Lemania 21.75 watch movement, utilized in mechanical timepieces circa 1980, features a manual winding system and a sweep second function. It offers a day and date display with quickset capabilities, allowing for easy adjustment. The design of the movement includes a separate drive for the train and hand gears, enabling a low profile and accommodating a larger balance.
