Abstract
The invention relates to a process for assembly of a crystal and a bezel for use of the crystal as vibrating and radiating element, according to which unconnected junction zones are determined and form the only mechanical link for transmission of vibrations of the bezel to the crystal, on which zones the crystal is secured on the bezel to transmit to the crystal any vibration communicated to the bezel. Outside these zones the crystal is held without direct contact with the bezel.The invention also relates to a crystal-bezel assembly unit for a timepiece comprising junction zones that form the only mechanical link for transmission of vibrations from the bezel to the crystal to cause the crystal to resonate under the action of the vibrations, and outside said junction zones the crystal has no direct contact with the bezel.The invention also relates to a timepiece comprising such a unit.
