Abstract
A timepiece mechanism including a movable component oscillating about a rest plane passing through a pivot axis. An arbor of the movable component includes a main protruding portion which forms the largest radius of the movable component about this axis. The protruding portion is delimited by two surfaces defining a profile inscribed in a rectangle whose shape proportion is greater than 2 wherein the direction of the length defines a main axis, which occupies a determined angular position with respect to the rest plane in the rest position of the movable component. The mechanism has a preferred direction of magnetization that is substantially orthogonal to the main axis of the arbor in the rest position.
