Cannot disable turn by turn?

Yesterday I tried using the watch for routing (normally I use a GPX file). I was not able to figure out a way to turn off the turn by turn navigation alerts

The repeated beep sound they make is horrible, but the worst part is that this functionality covers the map and I cannot see which exact "left" am I supposed to take. 

So if the question here isn't obvious: How do I turn this feature off? 
I'm fine with the small prompts telling there's going to be a turn on a few meters, but it's just ridiculous for this alert to take up the entire screen.
