The Alpina 870 is a manual wind watch movement that was in use around the 1950s. It shares many common parts with the Eterna 1057 movement. The differences between the ETA 761-764, 773, 838-841, 846, 862, 882, 1030, and 1040 are not known, but it is likely that these numbers were assigned to indicate variations in base plates, bridge layouts, and lever bridges.
