@Medic1559 a little bit of research before the purchase could have saved you from a lot of surprises.
My guess is that you’re coming from a Suunto Traverse. As far as I know this was/is the only watch with a red backlight.The vertical doesn’t have one.
You can’t increase the font on the watch face. In activity recording you can create a custom sportmode and define less fields. This will result in bigger fonts
There is no store for watch faces. The ones in the watch are the only one
Coordinate format options are still the same
