Abstract (en)

[origin: WO2016166006A1] Watch subassembly (200), including an arbor (10) comprising a magnetised or charged surface (16) pivoting in a housing (14; 15), and a polar weight (11; 12; 31; 32) subjecting this surface to a magnetic or electrostatic field about an axis (DA), a polar weight (11; 12; 31; 32) interacting axially with this surface to absorb a shock and then subsequently return the arbor (10) to its operating position, and creating, in proximity to the surface, a magnetic or electrostatic field that either attracts the arbor (10) radially toward a wall of the housing (14; 15) or varies along the axis (DA) and applies to the arbor (10) a resistive force resulting from the interaction between a polar weight (11; 12; 31; 32) and the surface.
