The Lemania 8818 watch movement, introduced in 1967, features a ball-bearing rotor and an alarm mechanism consisting of a hammer on a sounding spring. This movement offers an automatic/manual-wind alarm function, allowing for the alarm to be set either by manually winding it or by relying on the automatic winding mechanism. The watch itself does not have a manual wind function, relying solely on the automatic winding system. The alarm, on the other hand, requires manual winding. Other notable features of the Lemania 8818 movement include shock protection, a sweep second hand, and a quickset date function activated by a button positioned at the 2 o'clock position.
