Abstract
A watch assembly (2000) including a watch (1000), and a setting tool (200) driving an external drive mobile (20) so as to pivot around an external axis (DE) including an external multipolar magnet (21) engaging, to carry out a setting, with an internal multipolar magnet included by an internal control mobile (1) of the watch (1000) pivoting around a first axis (D1) and meshing with the entry of a reduction train (30) in which the exit meshes with an internal controlled mobile pivoting in the case (10), this setting tool (200) including means for counting the number of turns of the drive mobile (20) to precisely determine the pivot angle of the internal controlled mobile and/or means for determining and/or visualising the angular position of the internal controlled mobile.
Claims34
A horology assembly (2000) comprising at least one watch (1000) and at least one setting tool (200) arranged to enable the drive, with no direct contact, of an internal control mobile (1), which is pivotally mobile around a first axis (D1), comprised in each said watch (1000) in said horology assembly (2000), through a case (10) comprised in each said watch (1000), for carrying out a setting and/or an energy recharge, each said setting tool (200) comprising means for generating an external magnetic field rotating around an external axis (DE) and arranged to engage in complementary attraction or repulsion with internal magnetic or ferromagnetic zones (11) comprised in said internal control mobile (1) to rotate said internal control mobile (1), each said watch (1000) comprising an internal controlled mobile (2) pivotally mobile around a second axis (D2) inside said case (10), characterised in that, in each said watch (1000), said internal control mobile (1) comprises a control pinion (13) meshing with an entry mobile (31) comprised in a reduction train (30), in which an exit mobile (32) meshes with said internal controlled mobile (2).
A watch (1000) comprising a case (10) containing an internal control mobile (1) that pivots around a first axis (D1) and an internal controlled mobile (2) that pivots around a second axis (D2), characterised in that, in each said watch (1000), said internal control mobile (1) comprises a control pinion (13) meshing with an entry mobile (31) comprised in a reduction train (30) in which an exit mobile (32) meshes with said internal controlled mobile (2).
