I recently got this Garmin descent mk2i, wihch I use both for diving and day to day use. Because I am not used to wear a watch, my brain does not really calculate well the distances, and today morning I bumped into a door handle with my watch, which now has a small scratch in the middle. I think that it is quite shallow and does not affect the sapphire part, but I wonder whether it is safe to dive with it (my dives ar not deeper than 45 meters). Any thoughts on that? I attach a picture!
