Embodiment Construction

[0036] One object of the invention is to protect the oscillator from any magnetic interference.

[0037] The invention aims in particular to limit the magnetic interaction on the arbor or shaft 1 of the movable pivot member 10 of the timepiece mechanism 20 integrated in the movement 30 of a timepiece 40 , in particular a watch, and in particular on the balance, The pallet shaft and escape wheel arbor constitute the maintaining (escapement) and regulating (balance with hairspring) components of preferred application.

[0038]The invention is described here for this single application of a maintaining (escapement) component and a regulating (balance with sprung) component. A person skilled in the art, watch designer, will know how to apply the invention to other mechanisms.

[0039] The invention allows a watch with non-magnetic hairspring, pallet lever body and escape wheel to withstand a magnetic field of about 1 Tesla without stopping without affecting the mechanical propert...

Abstract

The shaft (1) has a set of aligned parts, where the shaft is arranged in a magnetically inhomogeneous manner, and is provided with a variation of intrinsic magnetic properties according to an axial direction of a fulcrum pin (D) of the shaft or in a radial manner with regard to the fulcrum pin or according to the axial direction and in the radial manner with regard to the fulcrum pin at the same time. A median part is surrounded on both sides of the shaft by two end zones according to the direction of the pin. An independent claim is also included for a clock element.

Description

technical field [0001] The invention relates to an arbor or balance shaft of a pivotally movable timepiece member, said arbor consisting of one or more aligned parts. [0002] The invention also relates to a pivotally movable timepiece member comprising such an arbor. [0003] The invention also relates to a timepiece, in particular an escapement, comprising such an arbor and / or such a movable member. [0004] The invention also relates to a timepiece movement comprising such an arbor and / or such a movable member and / or such a mechanism. [0005] The invention also relates to a timepiece, in particular a watch, comprising such an arbor and / or such a movable member and / or such a mechanism and / or such a movement. [0006] The present invention relates to the field of timepiece mechanisms, in particular of regulating components, especially for mechanical watches. Background technique [0007] The speed regulating part of a mechanical watch is formed by a harmonic oscillator ...
