The Gruen N225 is a manual-winding mechanical movement produced by Gruen. It features a pin-lever escapement, sweep second function, and a crown mechanism with a rocker bar. The movement includes a ratchet visible on the dial side and was primarily used in watches from 1950 onwards. It shares design characteristics with the Kienzle 48 family, suggesting possible technical cooperation between the manufacturers.
