摘要：
A method of measuring accuracy of a watch including a visual display device, including: storing a first instant, at which the display is in a first display position corresponding to a first image, with a corresponding time reference source; determining a first display value for the first image and stored in a storage in correlation with the first instant; storing, after a determined time interval, a second instant, at which the display is in a second display position corresponding to a second image, with the corresponding source; determining a second display value for the second image and stored in the storage in correlation with the second instant; and calculating displaying on a viewing device the variation in rate of the display.
