Abstract
Timepiece including: PA1 a spring (1a) housed in said barrel (1), PA1 an electric power generator (2) coupled to said barrel (1), PA1 a rectifier circuit (4) connected to said generator, and PA1 a regulator circuit (6) supplied by the direct voltage (Ua) from the rectifier circuit and intended to control the rotational speed of the generator (2). The rectifier circuit (4) comprises: PA1 a voltage doubler rectifier (20) connected to the output of the generator (2), PA1 a first capacitor (23) and a first diode (21) connected in series between said first output terminal (20a) of the rectifier (20) and the first output terminal (B2) of the generator (2), et PA1 a second capacitor (24) and a second diode (22) connected in series between the first output terminal (B2) of the generator (2) and the second output terminal (20a) of the rectifier (20)
