Fitness bracelet or smart watch for android - choose according to the parameters?

Question

Android

I am looking for a replacement for Jawbone Up - it is necessary that the watch synchronizes with an android-based smartphone, have the function of a smart alarm clock (woke up in the stage of shallow sleep) - and the function of monitoring inactivity - vibration at certain intervals would warn that you need to change the type of activity. This is what the joubon has and what I need and in the device I'm looking for. and now I will describe what he does not have, but I would like and maybe someone will help you choose the right gadget. So - in order of importance - 1) a heart rate monitor 2) water resistance 3) tighter integration with a smartphone - for example, call and message notifications like the Sony Smart band does - but it does not have a heart rate monitor and inactivity monitoring. I hope to find something in all this variety of devices.
