<p>The invention concerns a device in the form of a wrist watch which, besides its function as watch, operates currency conversion and computation of monetary values. The device which is compact and permanently available is designed to relieve the wide user public from the constraints of transporting and manipulating a pocket calculator or a currency converting apparatus. The invention is essentially characterised by the following features: an electronic chip (3) which, under the control of a master software, manages the set of the device active elements and in particular the currency conversion and computation functions; its display screen (7) which is provided with a mechanism such that a simple pressure on the part of the user on any point of the screen is enough to activate the conversion and computation functions; its microphone (6) and voice recognition function enable the user to make his processing requests orally; its button (5) which can be switched or pressed at will by the user at any time with a simple movement to change permanently or invert temporarily the current conversion parity; its screen which comprises a luminescent diode (8) displaying visually the processing requests and their results, by day as by night; its button cells (2) which guarantees great power supply self-sufficiency.</p> |
