An instrument case assembly may include an instrument case having a face, a back, and at least one side extending between the face and the back about a perimeter of the case. The face may include a crystal held by a perimetrical bezel. In some aspects, a pair of strap brackets may be removably coupled to the at least one side at substantially opposite perimetrical regions of the case. In some aspects, a crystal guard may be coupled to the case.

A device has a magnetically shielded component that is magnetically shielded from an external magnetic field, and a housing. The housing is made from a ferritic stainless steel that has an austenitized surface layer rendered on the surface, and an internal layer portion having an internal ferrite phase that functions as a magnetic shield for the magnetically shielded component.

An electronic device for a wristwatch including an electronic module provided with at least one sensor capable of measuring physiological data of a wearer of the wristwatch, and with an electronic control unit associated with the sensor. The electronic device includes a trim element acting as a case back and capable of being removably mounted on a case of the wristwatch, the electronic module being integrally housed within the trim element acting as case back. In one aspect, a wristwatch includes a case having a removable case back and a horological movement housed within the case, with the removable case back constituting the electronic device.

In a timepiece 100 having an antenna 3 and motors 4, each motor 4 includes a stator 41, a coil 42 magnetically connected to the stator 41, and a rotor magnet 431 disposed in a receiving part 411 of the stator 41. With respect to each motor 4 disposed in a predetermined range from the antenna 3, an individual antimagnetic plate 5 which is a belt-like antimagnetic plate configured to have a width equal to or greater than the diameter of the rotor magnet 431 and cover a portion of the motor 4 including the rotor magnet 431 is disposed.

An article such as wristwatch that has a contoured front face and a rear face that is generally flat or can be presented in a generally flat configuration can be intimately wrapped in a close-fitting transparent protective film of skin-wrapped plastics material. The wrapping extends continuously over the article's front face and is skin-wrapped to match the contour of the first or front face. It extends over the article's second rear face and has overlapping or non-overlapping edges on the rear face. It can remain essentially invisible so the wrapped object can be displayed as though it were unwrapped. It enables the wrapped article to be transported and handled without risk of being scratched or otherwise deteriorated and can be readily removed from the article when the need to protect its surface ceases.

In an electronic timepiece, a baseplate having a pair of opposed major surfaces, a magnetic shield plate disposed in continuous contact with one of the major surfaces and a stator disposed on the other of the major surfaces. A pin is inserted through the magnetic shield plate, baseplate and stator and includes a head portion bearing against the magnetic shield plate, and is engaged by a screw having a head bearing against the stator for fixing the shield plate, baseplate and stator between the head portion and the screw head. The shield plate includes an inwardly sloped aperture for receiving the head portion of the pin, and the head portion has a tapered peripheral surface complementary to the inwardly sloped surface of the aperture. The head portion is thinner than the shield plate and does not protrude beyond a surface of the shield plate, and because the shield plate is in continuous contact with the base plate it is not deformed by the head portion of the pin bearing thereagainst.

The present invention relates to a method for stabilizing the temperature of an instrument which consists in that the instrument whose temperature has to be stabilized, is brought into contact with a container containing a temperature stabilizing element which presents, in the considered temperature range, at least one transformation point, so that the latent heat of transformation, which produces an elevation of the calorific capacity at the time of the passage through the transformation point, stabilizes the temperature of the instrument.
