This will have some impact on the mechanical watch more or less, because the wireless charger uses electromagnetic charging, in charging, it will have more or less some electromagnetism, will have some impact on the mechanical watch, so in the use of wireless charger, the mechanical watch is best away from the charger slightly far away.
If it is a wireless charger, there is still some impact on the machine watch, because the wireless charger is electromagnetic, the battery has a certain impact on the mechanical watch, but the impact is not large.
