A device for determining a position of a horological display, the device including a control device coordinating a time base, a shape recognition device, and an optical acquisition device. The control device identifies the display and monitors its travel in order to code its instantaneous position in relation to a fixed guide-mark, and controls entries of its position at distinct instants in time to determine its mobility in relation to the fixed guide-mark. The device includes a device for determining the depth position of the display in relation to the fixed guide-mark, a device for controlling the position of the optical acquisition device, a device for controlling a focus of the optical acquisition device, and an additional optical acquisition device coupled with the optical acquisition device to interferentially monitor the display.

A communications system includes apparatus for generating a succession of time message signals, a central station having a transmitter for transmitting the time message signals, at least a first receiver for receiving the time message signals and timer circuits for determining the real time of receipt of each time message signal. Each time message signal is representative of the real time of receipt, by the first receiver, of a preceding time message. The first receiver includes a clock for providing the first receiver with an internal time signal. The clock is reset upon receipt of a first time message signal and is advanced, upon receipt of a subsequent time message signal, by the real time indicated by the subsequent time message signal.

A portable wireless telephone including a main unit of small volume to which an antenna, an earpiece and a microphone are connected. The means for composing a number to be called include a display system (4, 5, 13) in which the digits making up the number to be called can be displayed, one after another, by the manipulation of a crown (10). Such crown can be rotated (60) then pressed (61) in order respectively to choose a digit then confirm it and continuing thus until said number is entirely composed. The telephone can be advantageously combined with a timepiece.
