I have a 6S Pro, and I wear it during HIIT’s workouts. Every time that I see word “Kettlebell” in the whiteboard, automatically put a wristband over my watch to prevent any damage. Simple and cheap solution; the only downside is that you can’t see the data displayed on your watch; anyway, during the HIIT workouts I check my watch only a couple of times to see the HR.
