Abstract

Method for displaying the time in a wristwatch furnished with an electronic display (4) allowing the display of a simulated mechanical watch movement and of time indicators (20) so as to simulate a mechanical watch. The time displayed is advantageously calculated on the basis of the simulation of the movement and depends on the acceleration measured by an accelerometer.
