Abstract

The movement has a conventional cylindrical permanent magnet (1) and coil (2) surrounding and rotating about the axis of the magnet. The return spring (18) is spiral, coaxial with the magnet, and adjusted by rotating its fixed end (19). The counter drive is to a pinion (14) which is also coaxial with the magnet, and which is pref. hollow and driven by a pawl (12) on the coil shaft engaging a ratchet (13) inside the hollow pinion.
