Abstract: A balance wheel-hairspring oscillator (10) has a balance wheel shaft (18) intended to be pivotably mounted on a frame of a timepiece. A balance wheel (12) is secured to the balance wheel shaft (18). A hairspring (14) has an inner end (14a) secured to the balance wheel shaft and an outer end (14b) intended to be connected to a connecting member (16) to the frame. A transmission member (20, 22) is arranged to interact with an escapement. The balance wheel (12) and the hairspring (16) are arranged on either side of the transmission member.

Abstract: An electromechanical timepiece module (1) has a main plate (10) with an actuator module (40) driving at least one mobile part (30) by a gear train (42). The mobile part (30) displays a time or non-time function. A wireless communication module (2) is configured for transmitting and/or receiving a wireless signal. And a control unit (6) is configured for controlling the actuator module (40) depending on a received wireless signal. The mobile part (30) and the gearing (42) are made of an electrically conductive material and are in electrical contact with each other but electrically isolated from the remainder of the timepiece module (1). The mobile part (30) is electrically connected to the communication module (2) so as to act as an antenna for the transmission and/or reception of the wireless signal and to transmit the wireless signal between the mobile part (30) and the wireless communication module (2).

Abstract: A multi-functional portable device including a display module driven by an actuator and configured to be able to display one or more display functions simultaneously or sequentially. A control unit is configured to receive outside information and control the display module according to said one or more display functions, based on the received outside information. The device also includes a computer medium including portions of code for a software application having a plurality of display functions, each of the display functions being configured to be executed in the multifunctional device.
