TL;DR: In this article, a watch movement consisting of a motor barrel, a fusee, and a wire between the fusee and the motor barrel is described, with a main surface having a spiral groove.
Abstract: The watch movement comprises a motor barrel ( 102 ), a fusee ( 104 ) having a main surface that has a spiral groove ( 148 ), means ( 192 ) for winding the movement arranged to drive the fusee, a going train ( 200 ) arranged to be driven by the fusee, and a wire ( 106 ) extended between the fusee and the barrel. The watch movement additionally comprises a fixed guide ( 155; 255 ) and a winding roller ( 157; 257 ) mounted to slide on the fixed guide, wherein the winding roller is arranged to guide the wire when the fusee turns and to simultaneously assure the insertion of the wire into the groove ( 148 ) and its removal therefrom.
