Abstract: A horological movement includes an analogue time display, a gear train, a barrel driving the analogue display via the gear train, and an oscillator formed of a resonator, including a balance and a piezoelectric spring, and a mechanical escapement coupling the balance to the gear train. This horological movement further includes an electric energy source which is associated with the electronic control circuit, which is arranged to be able to control the application of an electrical supply voltage to the piezoelectric spring so as to excite the oscillator to obtain a functional oscillation of the resonator and then to maintain this functional oscillation. The mechanical escapement is configured so as to be an escapement for counting the alternations of the functional oscillation, so as to pace the running of the horological movement, without the resonator being able to receive from the barrel via this mechanical escapement enough mechanical energy to maintain the functional oscillation.

Abstract: A method for fabricating metal decorations on a domed dial made of insulating material, wherein the method includes the steps of forming a photosensitive resin mould by a UV LIGA type process, and electrodepositing a layer of at least one metal starting from the conductive layer to form a block, which substantially reaches the upper surface of the photosensitive resin.

Abstract: The present invention concerns a piezoelectric element (3) for an automatic frequency control circuit. The element includes a balance spring (7) formed of a strip of piezoelectric material, a first electrode connected to the automatic control circuit, and disposed on all or part of one side of the strip, and a second electrode connected to the automatic control circuit and disposed on all or part of another side of the strip of piezoelectric material. The element further comprises at least two discontinuous layers of an insulating material, each discontinuous layer of insulating material being disposed on at least one side of the strip of piezoelectric material and separating a first electrode from a second electrode. The discontinuous layers of insulating material are distributed on predetermined portions of the balance spring substantially forming arcs, with a predetermined angular periodicity.
