Provided is a micro-power generator suitable for a wearable, portable or moving electronic device, including a rotor wheel including a multipole magnetic array of a circular design, such as a multipole magnetic ring or disc, which multipole magnetic array has an inner radius r3 and an outer radius r4, at least one stator which is a multipole metal stator including at least one stator coil having a plurality of windings for producing an electric voltage, and a base plate onto which the rotor wheel and the stator are mounted. The at least one stator is fixedly connected to the base plate. The rotor wheel is pivotally connected to the base plate by a pivoting mechanism which allows for a rotation of the rotor wheel about a pivot axis perpendicular to a first plane in which the rotor wheel extends, which pivot axis preferably has a concentric orientation to the rotor wheel. The rotor wheel is provided on one side of the base plate, and the rotor wheel has a centre of mass that has an eccentric position with respect to the pivot axis.

To prevent an erroneous operation and improve operability, a button device and a timepiece including the button device are provided. The button device includes: a cylindrical first guide protector 11 protruding from the lateral face of a wristwatch case 1; and a first button 12 disposed in the first guide protector 11 to be slidable inward and outward of the wristwatch case 1. The first button 12 includes a first button head 13 disposed in the first guide protector 11, and a first button shaft 15 passing through a first through hole 14 of the wristwatch case 1. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1. The first guide protector 11 protects the outer periphery of the first button head 13, and this prevents accidental and erroneous operation of the first button 12. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1, and this allows the user to easily place a fingertip on the outer end face of the first button head 13, and so improves the operability of the first button 12.

A timepiece movement includes a photovoltaic cell which is attached to the upper surface of a support plate, preferably by adhesive bonding. On the other side of the cell, on its lower surface, the support plate is provided with a plurality of nuts. An electrical module including a flat surface is attached to the support plate with the nuts. The module is provided with several openings whose position and dimensions correspond to those of the nuts, so that the nuts pass through the openings, allowing the flat surface of the module to be placed in contact with the support plate. The module is secured to the support plate by screws, screwed into the nuts. The connection via the nuts secures the photovoltaic cell to the electrical module and ensures shock resistance, without requiring a lateral support.

The first wheel is in meshing relation with the rotor of the generator and is fixedly connected to the oscillating mass, on the side opposite the analogue time display, so that this oscillating mass can rotate the rotor of the generator via the first wheel.

An electronic timepiece includes an exterior case; an electronic module housed in the exterior case; a winding stem projecting from the electronic module to the exterior case; and a conductive earth member having a plate-like portion and an elastic portion extending from the plate-like portion to a winding stem side, in which the winding stem has a flange disposed between the electronic module and the exterior case, and the elastic portion is brought into contact with a surface of the flange on an electronic module side in a state where the winding stem is pushed into the electronic module.

An electronic watch including a movement, and the movement includes a movement main body, a plate manufactured by a ferromagnetic metal, and a hook having flexibility, and the plate includes an engagement part that protrudes from the rear surface of the plate and which is configured to accommodate one end part of the hook, and the one end part of the hook is configured to be accommodated by the engagement part by elastically deforming the hook, and the other end part of the hook is fixed to the movement main body.

A display panel includes a plate-shaped decoration member including a shading part and a light transmission part formed within the shading part, as well as a plate-shaped reflection member disposed on a back side of the decoration member. The shading part and the light transmission part create a fine pattern in plan view. The reflection member is configured to reflect light. The decoration member is disposed on a front surface of the reflection member.

In a motor, a magnet is configured so that four pairs of S-poles and N-poles are formed at equal angular intervals, and a stator core has six salient poles formed thereon. Of the plurality of salient poles, when the first salient pole or the second salient pole faces a position between an S-pole and an N-pole, the other salient pole faces the center of an S-pole or the center of an N-pole.
