Title: Shock absorbing pivot bearing for rotary watch parts

Abstract: The pivot 28 is journalled in a bearing member 38 molded in one piece with a resilient web 39 fixed at its periphery to a body member 41 by a hard metal ring 42. Due to the resilience of web 39, member 38 may be shifted into member 41 and tilt about a diameter of its edge connected to web 39, thus protecting pivot 28 against impacts occuring in any direction. Ring 42 constitutes abutting means which limit the amplitude of the displacements of shaft 1 under the action of impacts.
