I have a watch like that and it doesn't have a touchscreen - it doesn't need one from my point of view.

Forerunner has no touchscreen. As far as I know only Vivoactive is with touchscreen equipped. For my experience, there's no advantage with touchscreen as there are too often mistouches during the activity, which can in worst case reset your current exercise.

In the Garmin online shop you can see relatively well which watches have a touchscreen.
In the case of the Forerunners, for example, these are the new 265 and 965 models.
