Abstract: A watch incorporating an assembly (70) including a light sensor (72), including a photovoltaic cell, a negative electrode (78) and a positive electrode (79). The assembly has a first portion (52A), in which the electrodes are arranged, and a second portion (54A) which is not included in the first portion and which comprises or covers an antenna (80). The semiconductor material wafer extends into the first and second portions, and all the electrodes are arranged below the semiconductor material wafer. Preferably, this semiconductor material wafer or layer has no conductive doping in the second portion. The wafer, or layer, determines, together with additional layers provided thereon, the homogeneous colour and uniform appearance of the assembly from the side of its upper surface. Also, a dial formed by such an assembly.

Abstract: A non-acoustic alarm for a portable object includes an electromagnetic motor which can be electrically controlled in order to generate a vibratory effect. The electromagnetic motor includes a movable magnetic circuit and a stationary magnetic circuit. The movable magnetic circuit includes a coil, a ferromagnetic core coupled to a magnetic cage forming an extension of the ferromagnetic core. The magnetic assembly of the movable magnetic circuit constitutes a movable magnetic mass of the non-acoustic alarm capable of generating the vibratory effect. The non-acoustic alarm includes resilient connection elements resiliently connecting the movable magnetic circuit to the stationary magnetic circuit. The resilient connection elements are shaped to guide and ensure that the movable magnetic circuit undergoes a linear, or quasi-linear, oscillatory motion during the electrical control of the electromagnetic motor.
