High-quality 8 Watch Winder with 8 Extra Slot with Built-in Illumination

You can set the number of Turns-Per-Day from 300 to 2300 TPD. Two buttons are used to turn up and down, the up button increases by 50 each time, over 300 TPD returns to 2300 TPD cycle.

Direction: clockwise/counter clockwise/clockwise+counter clockwise

TPD Calculation Method: 10 turns per cycle

24-hour mode operating cycle (minutes) = 1440/ (TPD/10 turns);

12-hour mode operating cycle (minutes) = 1440/ (TPD/10 turns) /2;

8-hour mode operating cycle (minutes) = 1440/ (TPD/10 turns) /3;

e.g: TPD set to 650, clockwise, 24 hours mode. Then the running period (minutes) =22.2, that is, each cycle is 22.2 minutes.

Cycle execution: the time required for the motor to rotate clockwise 10 times + the motor stop time = 22.2 minutes. In the 12 (8 hours) working mode, the cycle runs for 12 (8 hours) hours and then stops; stops for 12 (16 hours) hours, and then restarts the cycle.

Note:

There is no magic number of rotations that will wind your watch. Things such as how active you are, how many complications your watch has, how frequently you use the chronograph function, how frequently you wear your watch, the watch make, how long it has been since it was last serviced and a host of other variables will impact what your watch requires to stay wound. And a watch winder won't wind a watch that is fully stopped. So, you need to manually wind the timepiece to get it running first. You will have to make this determination by trying the various settings.
