Abstract

The timepiece, which is preferably a wristwatch, includes for each time position a capacitive sensor (C1 to C12), on a fixed bezel, including only four markings (R3, R6, R9, R12) at 3 o'clock, 6 o'clock, 9 o'clock and 12 o'clock, and a single crown-push-button (9). The case contains, in particular, a non-acoustic vibration generator (20) and an electronic interpretation and coding circuit (15), associated with a time-keeper circuit (10), with the sensors and with the crown to control the vibration device, said circuit (15) being designed to identify the manipulations on the crown (brief, long application of pressure or pull) and on the sensors (positioning or movement).
