The ETA 1011 is a hunter calibre watch movement with a set-lever spring positioned between its plates. It offers several options such as a bimetallic screw balance, Breguet hairspring, and Reed's regulator. The lever and escape wheel can be made of either brass or steel. The differences between the 294 and 1722 variants are unknown. The movement supports the functions of stem winding and setting, as well as featuring a sub-second display.
