Answer 1

Yes you can but you will have to write an android wear app for your watch unless your strap has one already:-

If you have a Bluetooth Smart accessory, open its app on your watch and follow the app's instructions to pair the accessory to your watch.

Answer 2

BLE protocol only allows the communication between a central and a peripheral device. The wristband surely is a peripheral device that advertises BLE packets and expose some services (for example the heart rate).

You need to figure out if the android watch support BLE in central mode. In that case you will be able to scan for advertisement packets coming from peripheral devices (wristband), and connect to them.
