The Unitas 83 watch movement is a manual wind movement that was in use around the 1950s. It shares many parts with the Eterna 1057 movement. It is grouped with movements such as 761-764, 773, 838-841, 846, 862, 882, 1030, and 1040, although the specific differences between these movements are not known. It is likely that the numbering system is used to indicate variations in base plates, bridge layouts, and lever bridges.
