Abstract (en)
[origin: EP1821163A2] The watch has an oscillating mass which is free to rotate around a fixed rotation axis with respect to the watch. An electric generator e.g. micro alternator, is driven in rotation by the mass. An electric energy storage module e.g. lithium-ion storage battery, is electrically connected to an output of the generator. A movement is supplied by the module and has a display module that is visible on a side of the watch. The module and the mass are disposed side by side at the same level. A glass (30) permits the vision of the mass from a front side of the watch.
