How does everyone find the heart rate tracking accuracy? Reviews are a mixed bag and if i get one I'd like to know it's fairly accurate for running and gym etc?
The (dozens) of reviews I have read confirm the following:
- Watch 2 is the same as Watch 1, which is on par with all other smartwatches with an optical HR sensor, but not as good as a bluetooth chest strap.
- Watch 2 should have better longevity for the sensor than Watch 0 and Watch 1, as only it has full ceramic back protection covering the sensor, and not composite materials which are apparently very scratch prone.
/fine for me.
