Abstract

The method involves selecting a visual display device of a timepiece (10) as an experimental display. Measured instants at which the display is in display positions corresponding to images are respectively stored in correspondence with an inner/outer time reference source (3). Display values respectively corresponding to the images are determined. The values are stored in a memory in correlation with the instants. The temporary difference displayed between the values is calculated by a calculating unit (6). The deviation in rate of the display is calculated and displayed on a viewing unit (7). An independent claim is also included for a device for implementing a timepiece precision measuring method.
