How will Apple Watch use data from iPhone?

As far as you cell provider is concered it doesn't matter since data is data. If it ultimatly comes or goes through your provider it will count whether the aWatch uses Hotspot or BT.

Depends on what you're doing with the watch.

Normally, the data flow would be simply between the watch and the phone. So notifications, weather updates, time update, viewing gallery photos, etc ... i.e. info that already exists on the phone... should not use up more data.

Now, if you wanted to display Maps, then of course the phone (or the watch via the phone) will have to use up your data allowance.

I imagine it'll use Bluetooth to communicate.

It will have to use bluetooth. Not everyone has data plans that allow for tethering.

Interesting that they didn't include at least 802.11n. B/g seems very outdated, especially now with AC gaining traction.

Because it's not for connecting to a WiFi and your aWatch will not connect to your Mac/PC. It is just a aWatch to iPhone hotspot a lot like AirPlay. Just like AirPlay the aWatch/iPhone will be using BT and WiFi to communicate to each other but it will be invisible to you how it's working.

It looks like you will have an App on your iPhone that will be the aWatch App/control/setting/.... interface to the aWatch.
