A wearable object (42) including an electronic unit and a power supply unit formed by an electromechanical converter (6A) which includes a rotor (44) carrying first magnets (10A), a mechanical resonator (12A) provided with an inertia mass (46) capable of oscillating at a relatively high resonant frequency and carrying second magnets (20), and coils arranged so that, when the mechanical resonator is oscillating, an induced voltage is generated in these coils. The electromechanical converter is arranged so that the first magnets and the second magnets can, during a rotational drive of the rotor, interact magnetically so as to apply to the inertia mass, momentarily or temporarily, a magnetic force torque allowing to excite the mechanical resonator, in order to generate at least one oscillation of this mechanical resonator at its resonant frequency in order to generate a relatively high induced voltage allowing to recharge an accumulator.

An external battery device is implemented which can detachably engage with a smartwatch to thereby enable seamless battery replacement and smartwatch battery replenishment without having to remove the smartwatch from a user's wrist. The external battery device can be a bezel that aesthetically fits in a cut-out around a perimeter of the smartwatch's face and locks in place using, for example, a male-female connection mechanism. The external battery device includes a casing that functions as the bezel for the watch. The casing includes a channel inside which a rechargeable battery is positioned. The male connectors of the external battery device extend downward from a hole in the casing to engage with corresponding female receptacles on the smartwatch. In typical implementations, two different shapes of the male and female connection mechanisms may be used to provide a consistent manner in which the user connects the external battery device to the smartwatch.

A watch including a watch case provided with a case middle, the case middle carrying an element provided with at least one index and defining an inner cavity. The watch further includes at least one pair of electrodes and at least one light source device connected to the electrode pair and arranged opposite the index, the electrodes of the electrode pair being fixed inside the inner cavity, the element being water permeable such that, when the watch is immersed in seawater, the seawater can penetrate the inner cavity so that the electrode pair and the seawater form an electrochemical cell, for powering the light source device.

A horological movement provided with a generator and a circuit for regulating the frequency of rotation of this generator, the regulation circuit being arranged to be able to detect the zero crossings of an induced voltage generated in the stator by the rotating rotor and to generate first braking pulses which are triggered after zero crossings and each end before the induced voltage reaches a peak value, preferably before the rectified induced voltage reaches a power supply voltage provided by a power supply capacity. In addition, the regulation circuit is arranged so as to be able to further generate second braking pulses each of which occurs after detection of the end of a charging period of the power supply capacity during which the induced voltage reaches a peak value and each end before the induced voltage crosses zero.
