The Roamer 468 is an open face calibre watch movement with a bimetallic screw balance featuring four adjustment screws and a Breguet hairspring. It includes an on screw riveted washer for lifting the balance cock during unscrewing. The 403L has minor differences compared to the 467L. This movement offers functions such as stem winding and setting, and a sub-second display. It was primarily used around 1956.
