Abstract: A watch case includes a middle having a first opening receiving a crystal, opposite a second opening receiving a back. The back is held such that it bears against an annular bearing surface of the middle by a threaded ring cooperating, by screwing, with the middle. The back includes a first indexing element to cooperate with a second indexing element with which the middle is provided so as to immobilise the back in a single angular position such that it cannot rotate relative to the middle.

Abstract: A transducer device of a wearable object or as a wearable object as such, includes means for generating a first action in a first operating mode related to a specific function of the wearable object under the control of a processor or microcontroller processing unit of an electronic circuit being powered by a DC voltage source. The means for generating is configured to generate a second communication action in a second operating mode different from the first operating mode so as to obtain a dual-mode transducer device. The second operating mode allows information or data communication signals to be communicated mainly to the outside of the transducer device so that it can be detected by a monitoring unit of a monitoring system, is able to establish communication, and can receive data or parameter signals from another transducer device. The communication signals are ultrasonic signals transmitted into a water body.

Abstract: A horological movement including a mechanical resonator and a hybrid escapement including an escapement wheel and a pallet assembly with at least one magnetic pallet-stone formed of a magnet and associated with a mechanical banking, the escapement wheel including a periodic magnetised structure defining increasing gradients of magnetic potential energy for the magnetic pallet-stone, and protruding parts associated with the increasing gradients of magnetic potential energy. When the force torque is equal to a nominal force torque or has a value within at least an upper part of a given range of values, one of the protruding parts of the escapement wheel is subjected to at least one shock on the mechanical banking of the pallet assembly after the magnetic pallet-stone has climbed any one of the increasing gradients of magnetic potential energy, thus dissipating at least partially a kinetic energy of the escapement wheel.

Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ΔE in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.
