Does anyone know how to add music to a Padgene smart watch the generic ones... I'm usually good at figuring tech out but haven't been able to figure this out.

It looks to be a Bluetooth device. You would need a compatable Bluetooth device and sync it to exchange data. If you don't have Bluetooth on your wireless device you can get a Bluetooth adaptor and make it work that way.

The music won't actually be on the watch... it would be on your cell phone it communicates with. That type of watch is essentially useless without the device that it communicates with that does all the work. Look at it like a fancy wireless touchpad with a little display on it.
