The Peseux 7046 is an open face calibre pocket watch movement available in options including a bimetallic screw balance and a Breguet hairspring. It was manufactured in sizes ranging from 18.5 to 19''', with heights varying from 4.2 to 5.9mm. There are different bridge layouts, two base plates with differing dial-feet positions, and two slightly differing setting-lever springs. The movement is grouped under FHF 1 to FHF 16, with individual designations starting from FHF 22. The specific assignment of these differences to the FHF groups and calibres is partially known. The Peseux 7046 movement features stem winding and setting, sub-second display, and was commonly used around 1940.
