DEVICE FOR WINDING UP A WATCH WITH SELF-WINDING MECHANISM

摘要

Device (300) for winding automatic watches, comprising at least one electrical power supply means or an electric accumulator cell, and at least one support (301) acting as a receptacle for a watch, said receptacle support (301) comprising a bearing surface (302) intended to have the back of a watch resting against it. Said device (300) comprises means (310) of generating a magnetic and/or electrostatic field which means are placed in a fixed position underneath said bearing surface (302) and generate, at least in one angular sector (304) of a substantially annular emission zone (303) at least one magnetic and/or electrostatic field directed orthogonal to said bearing surface (302) and of intensity and/or direction that can vary as a function of time. Watch (200) comprising an automatic winding mechanism (10) with an oscillating mass (1) comprising a ferromagnetic internal first part and a peripheral second part made of heavy metal, and/or a paramagnetic conducting disc (20) coaxial with said oscillating mass (1).
