New ‘Polar Grit X’ Caliberates, On Par, With My ‘Garmin Fenix 6’.

Polar Grit X ‘all black’ at LEFT.
My Garmin Fenix 6 has the Titanium Bezel.
When in ‘smartwatch’ mode they are very DIFFERENT.
Like chalk & cheese.
As you can see from the top 3 pictures the distance & time were on par with my Garmin Fenix 6.
I can’t say which one is more accurate, but I know that the Garmin Fenix 6 is ‘OK’ — in that I have tested it against multiple other watches, including the new Fitbit Charge 4 (just a couple of weeks ago).
If the Grit X readings had differed widely I would have been concerned. They did not. They stayed within ‘spec’.
This was also true for the elevation & Heart Rate (HR) data. The Polar & Garmin were pretty close to each other.
So, that is good. That is a start.
I will publish more pictures and data soon.
This was a first cut after having the Grit X for 2.5-days.
