see this is what I'm saying.. typically apple will list it if it was compatible... it was nowhere in the 12w power brick and ironically not even listed in the 5w LULZ.

I didn't bother to check the 5W charger, since that's what came in the box with the Watch. However, since the watch is not listed even on the 5W charger page, I'm guessing that it's either an oversight or the pages just haven't yet been updated.

Now, since I charge my devices at night (when I am not using them and don't anticipate a sudden need), I use the chargers that came with the devices to charge them. YMMV
 
.....So it could be in your head (perception is a wonderful thing) OR it could be charging faster, which actually damaging your device...

No it couldn't. Please don't encourage him.

...The logic components in the battery of models prior to the 6 do not support that many watts and can be damaged easily by forcing (more than) twice the capacity across the line......

Chargers don't force current into devices.
Devices pull current from the charger.

Apple devices actually communicate with their chargers by looking for different resistance levels on the USB data pins.
If a pre-iPhone 6 sees one level it pulls 1A. If it sees a different level (or the wrong level) it pulls 500mA. That's why iPhones may charge slower with really old or knockoff USB chargers. They drop down to the USB standard of 500mA. That's also how the same iPad knows not to try and pull 1A out of a PC laptop port (thus damaging it) while also knowing that it is safe to pull 1A out of a MacBook USB port.
Now if the poorly made charger is putting out the wrong voltage -- that could surely damage the device.

I use a third party 10W dual USB port charger for my watch and phone by my bedside. No issues. Haven't checked charging speed but I assume the inductive charging method on the watch is the limiting factor.
 
I usually give away the 5W adapters that come in the box with my devices to friends. I like having just 12 watt chargers around, makes life simpler, knowing that any charger I have is capable of charging at the quickest rate any device I have (including my bike lights). At home, I have a power strip that had USB ports on it and I just plug a watch cable into that. No need to care how many watts it outputs and don't need to deal with a $19 wall wart in that case.
