    Abstract: Shock resistant bearing for a timepiece including an elastic structure and a central portion carried by the elastic structure, the central portion having a blind hole intended to receive a pivot of a rotating wheel set of the timepiece. The elastic structure and the central portion are formed by a single-piece part formed of single crystal quartz and the blind hole has at least partially the shape of a truncated or non-truncated trigonal pyramid against which the end of the pivot abuts. The invention also concerns a method of manufacturing a shock resistant bearing of this type wherein the single-piece wafer is machined in an anisotropic etching bath for single crystal quartz. Preferably, two masks are respectively arranged on the two sides of the wafer to simultaneously etch the quartz from both sides.
