When will music download to watch?

I often charge my watch and my phone separately.

The watch app says „Music is downloaded when Apple Watch is connected to power and placed near your iPhone“ - does anybody know how near it has to be? Will the same wifi network be ok, or does it have to be bluetooth distance, or actually within a few centimeters/inches?

Wifi is working fine, even faster than when it‘s in Bluetooth range
