Use some surgical tubing and loop it all the way around the front below the compass then attach to the face side to keep it protected.
When I was in Israel there were a lot of neoprene octopus holders, one loop or hole to go around a BC strap, the other for the mouthpiece to go through. You could do the same think here, as long as the hole was big enough for the compass to go through. The streach in the neoprene kept it in place but allowed it to be pulled out.
