The Fontainemelon 108 is a mechanical watch movement introduced around 1970. It features a stem mechanism without a setting-lever spring. Notably, the train and hand gear are driven by the barrel separately. The movement includes a manual wind function, a sweep second, and a day-date display. The day function can be adjusted by +/-24 hours, while the date can be quickly set using reverse setting. Additionally, the movement is equipped with a jeweled lever.
