The Eterna 1248UC watch movement is a detached manual wind movement that was utilized around the period of approximately 1960. It features an automatic function, a sweep second hand, and a date setting mechanism that requires the hands to be set 24 hours in order to change the date. It is worth noting that the earlier model of this movement included two date jumpers which allowed for quicker date setting by setting the hands back and forth between 20:30 and 24h.
