Abstract
A wristwatch (1) includes a keyboard whose control keys (4) are distributed over the length of the wristband (3), a processing unit (19) for data introduced via the keyboard, at least one display device (6) for displaying time functions and/or data provided by the processing unit, and a power source for the electric power supply of the electronic components of the wristwatch. In order to allow the use of its keyboard, the wristwatch (1) is placed on a work surface, the length of the wristband (3) facing a user. The display of the alphanumerical characters (7a) occurs in the direction of the length of the wristwatch, i.e., rotated by 90° with respect to the usual time display (7b). At least one integrated encoding circuit (9) acts as a communication interface between the keys (4) of the keyboard and the processing unit (19) integrated in the case of the wristwatch. The encoding circuit is placed in the wristband (3) and communicates with the unit via one of the two electric supply wires of said circuit. The distribution of the keys of the wristband may change as a function of a determined country.
