You know how to activate or download the Clock quard like a photo on the home page of Forerunnig 945 with Analog and digital clock dial
My guess is that this watchface shows the 945LTE watch. Which is kind of a different watch with a different default watch face...
Normally you can‘t get the faces from a different watch, unless someone else „makes“ a look-a-like on the IQ Store.
Also be aware, that the 945LTE is not available everywhere, so it can be, that it‘s not shown, depending on your country settings, I guess.
