The ETA 2325 watch movement is an open face calibre featuring a pin-lever escapement. It incorporates a coarse imitation of balance screws and includes a ratchet on the dial side. Additionally, it incorporates a hidden crown mechanism with a rocker bar. The movement was originally designated as ETA 2325, but has since been renamed as Kienzle 46. This movement is designed for stem winding and setting, with a sub-second function. It also offers the option of a digital display indicating minutes and jumping hours. The ETA 2325 movement was primarily used during the approximate period of 1940.
