Further, the image analysis software may call the microprocessor to calculate a time difference Δ t = t1-t2 between the actual time t1 and a display time t2, and store the calculated time difference Δ t to the storage module.
Furthermore, the mobile phone and the watch both comprise wireless communication modules, and the wireless communication modules of the mobile phone and the watch are connected in a matching mode.
Further, a time threshold T is set in the controller, and after the controller receives the time difference Δ T transmitted by the mobile phone, the controller controls the stepping motor to adjust the entity pointer and start timing at the same time, wherein the adjustment amount is Δ T + T.
Further, if the stepping motor controls the entity pointer to complete the adjustment amount within the time threshold T, the controller controls the entity pointer to stop rotating until the controller times the time threshold T, and the entity pointer starts to rotate again.

The operation of the system is described below by way of example:
example 1:
the dial plate of the watch is photographed by using image analysis software of the mobile phone, the image analysis software acquires an image of the dial plate, records the actual photographing time t1 at the same time, such as 3 minutes and 20 seconds when t1 is 5 minutes and 20 seconds, and stores the actual photographing time t1 in a storage module of the mobile phone.
The image analysis software analyzes the acquired image to obtain the display time t2 of the dial plate, for example, t2 is 5 hours, 2 minutes and 55 seconds, and the display time t2 is stored in the storage module of the mobile phone.
The image analysis software calculates the time difference Δ t = t1-t2=25 seconds.
The mobile phone transmits the time difference 25s to the watch through the wireless communication module, and the controller of the watch adjusts the pointer after receiving the time difference and starts to time from 0 at the same time. The time threshold T =30 seconds is stored in the controller, then the adjustment amount is Δ T + T, i.e. 55s, 55s is positive, then the dial hand is rotated forward (clockwise) for 55 s.
When the adjustment is finished, if the time counted from 0 is within the time threshold value 30s, the controller controls the pointer to stop rotating until the counted time reaches the time threshold value T.
Example 2:
the dial plate of the watch is photographed by using image analysis software of the mobile phone, the image analysis software acquires an image of the dial plate, records the actual photographing time t1 at the same time, such as 3 minutes and 20 seconds when t1 is 5 minutes and 20 seconds, and stores the actual photographing time t1 in a storage module of the mobile phone.
The image analysis software analyzes the acquired image to obtain the display time t2 of the dial plate, for example, t2 is 5 hours, 5 minutes and 20 seconds, and the display time t2 is stored in the storage module of the mobile phone.
The image analysis software calculates the time difference Δ t = t1-t2= -120 seconds.
The mobile phone transmits the time difference 25s to the watch through the wireless communication module, and the controller of the watch adjusts the pointer after receiving the time difference and starts to time from 0 at the same time. The time threshold T =30 seconds is stored in the controller, then the adjustment amount is Δ T + T, i.e. -90s, -90s is negative, then the dial hands are rotated backwards (anticlockwise) for 90 s.
If the timer counts from 0 to 30s and the wall is not adjusted completely, the controller starts the counter to count from 2 according to a natural number, counts once every other time threshold T, increases the adjustment amount by 30s every other time threshold T, and if the counter count value is 5, the adjustment is completed, the adjustment amount is-120 s +5 + 30=30, namely the final actual adjustment amount is 30 s. After the adjustment is finished, the controller controls the pointer to stop until the time reaches 5 × 30s =150s, and then the controller controls the pointer to continue rotating.
