can you use apple watch without pairing to iphone?

You have to setup your watch with iPhone. But you can use it without paring it. You can track your fitness, set alarms, see the clock, listen to music and see your heartbeat. But it is designed best to work with and iPhone 5 and higher.

Essentially no. Your watch has to connect to an iphone to be of any use.

Once you do pair your watch and phone and you are in a known wifi area, you can turn off Bluetooth and your watch SHOULD connect directly with wifi. I've found it doesn't always connect.

As of right now my bluetooth on the phone is OFF and I'm on wifi and can get notifications, play games, imessages, check instagram, etc etc.

To setup the watch you have to pair it with an iPhone. Once that is done it can however do several things even if the watch is out of range of the iPhone: http://help.apple.com/watch/#/apd0443fb403

Pairing it with an iPhone is required to set up the watch. That said, once the watch is paired with a phone it will function with minimal features (basically timekeeping functions) but all you'll have will be a fancy digital watch with fun faces and swappable bands.

No. You must pair it before you can use it.

Yes

Still No Hayden.
