@ajaxus it depends on the exercise. There are exercises which for which you will hold kettlebell on the inside of your arm. You may try to perform some of the exercises with light kettlebell and slow to see whether it is going to be safe for a watch. Personally, I stopped using watch during kettlebell workouts since Ionic (I encounter the same problem and my watch got a few hits). Back then it was part of my weight-loss regime so I was counting calories. What I did instead was using external HR monitor like PolarH10 or OH1, and let PolarBeat app on the phone track the workout. Then I added the same workout manually to Fitbit with calories specified by the PolarBeat. Not ideal but safer for the watch. But that will not add AZM if you care about that (although knowing Versa 4 HR issues that would be the problem regardless for kettlebell workouts).
