The Langendorf 1262 watch movement is an automatic movement with a period of usage starting from 1957. It is based on a modified Peseux 335 base movement and features two roller freewheels for smooth winding. The movement includes a jewel-bearing rotor and an on top jewel bearing for the barrel. Additionally, it incorporates automatic functionality as a module on the base movement. The movement also includes the functions of an automatic winding system and a sweep-second hand, but does not elaborate further on their specific details.
