(4) The watch winder cannot wind my movement, why?
First, make sure your mechanical watch has an automatic movement winding feature.
Program 4 is not suitable for mechanical watches with low efficiency, in the worst case
the watch will break.
(5) How do I put my watch on the watch holder correctly?
Remove the memory foam holder from the rotary plate, place your watch around it, close
the strap and place the holder in the groove. If you cannot put your watch around the
mount normally (because the strap is too short), use force to buckle the watch as the
memory foam can be reshaped.
(6) Why is there no battery compartment in the watch winder?
This product is equipped with a USB power cord, so it can be charged by the mobile
phone power adapter or a power bank, the durability and economy of which is several
times higher than that of a battery. The charging capacity of the watch winder is around
1500-2100 mA (as much as five conventional 1.5 batteries). A traditional power bank has
a capacity of about 10000-20000 mA, so it can be used for repeated charging.
