<p>The timepiece has an escapement mechanism for driving a finish gear-train of a watch movement defining a reference plan. A balance (42) co-operates with the escapement mechanism and is mounted in a frame (28). The frame is pivoted around an axis with respect to the reference plan, where the orientation of the frame, with respect to the axis, depends on the orientation of the gravitational force of the earth.</p> |
