THE AMAZFIT GTR 47MM
Because of the brown leather strap, the stainless steel version (just like the aluminum version) of the Amazfit GTR is ideal for use even with more formal outfits/attires.
The 47mm in diameter case accommodates a 1.39 inch AMOLED screen (454x454p/326PPI) which although not the largest we've seen in a smart watch still it sits well on my arm.
To have a better understanding about the size of the AMOLED screen and the diameter of the case we placed the Amazfit GTR 47mm right next to the new THOR 5 by Zeblaze (1.39" AMOLED screen - review soon), the Alfawise/Kingwear KW88 Pro (1.39" AMOLED screen) and the THOR PRO (1.53" IPS screen) again by Zeblaze.
The case of the stainless steel version features a mirror-like polish so if you don't like that then the dark grey aluminum version could suit you better.
Two buttons are located on the right side of the case, the top one which can be used to turn the screen on/off, return back to the dial and turn the watch on/off and the bottom one which can be used to access the various sports functions/modes.
It's also worth pointing out that the brown leather strap used in the 47mm version is 22mm wide whereas the one used in the 42mm version is 20mm wide.
At the rear of the Amazfit GTR we find the BioTracker PPG biological tracking optical sensor.
