Activity wristband

[kasugatei]

I am trying to find a quite specific product. I am looking for activity wristband, but febore everyone starts to recommend me Fitbits etc., here are the requirements:
- long battery life (at least 2 weeks). Non chargeable models are ok if the battery can last at least 1 year
- must work with Apple Healhtkit
- no display
- pedometer + heart rate monitor
- reliable

I recently got Xiaomi Miband 1 which is missing heart rate monitor and pedometer doesn't seem precise enough so I plan to use it for now. I am also fine with one of those monitors which can fit below the classic watch. On everyday basis I prefer to wear my "stupid" watch so I don't want smartwatch. Also, I have a sort of smartwatch by Garmin, but I use it only for going to the mountains. Any first hand recommendations?

So I found one that meets all but 1 of your requirements, this thing.

thanks for the effort, but it is more watch than the bracelet....
