Sony Smartwatch 3 has NFC (and GPS). Too bad it's rather ugly. AFAIK, it only currently uses NFC for pairing to a phone, but the hardware is there and Android Wear will hopefully soon include complete support for it, like they recently did with watch GPS support.

Unfortunately it is only a passive tag for pairing. You can't to do anything else with it, so it cannot read other tags itself.
