Abstract: Interaction methods between a smartphone and a timepiece having two analog-type pointers, each of the pointers being controlled independently by a stepper motor, the timepiece and the smartphone being able to be in communication through a wireless remote short-range communication link, the calibration method comprising the steps of S1- capturing image(s) of the watch with the smartphone, S2- processing the image(s) to determine accurately the displayed angular positions of the pointers, S3- send correction data from the smartphone to the watch, S4- carry out, at the watch, an appropriate correction so that the pointers are caused to display the current absolute time, the absolute time set method comprising the steps of S11- send absolute time reference from the smartphone to the watch, S12- carry out, at the watch, an appropriate correction, to update the internal counters and positions of the pointers so that the pointers display the current absolute time.
