There is a new Pro version out which is why this price coming down.
Still $350 at most stores and $399 at JB here in Aus.
It has mic and speaker to take bluetooth calls on watch which is good for those without bluetooth in car as you can avoid fine for using phone while driving since your not going get busted for touching your watch!
fyi - OS is NOT 'Wear OS' (aka google/android watch) by google
