Looking for a smartwatch

[TribalLoser]

I'm looking for a smartwatch that has limited or no GUI with:

• 
  1. Heart rate monitor
  2. GPS
  3. Call notifications (even if I can't see what the text says)
  4. Vibration/alarms
  5. Long battery (about 3-4 days)
  6. Sleep tracking

I've tried the FitBit Flex, but it's missing half of the features I need. Mainly I want something that isn't bulky

P.S. Yes, I did number them according to their importance

I'd like I specific product, please and thank you
