If you’re digging into the sand with your hands and your watch on, you’re going to get sand lodged in the digital crown. I’d be careful when dislodging that sand, at the very least. I certainly wouldn’t make an habit of the activity. Personally, if I was going up to my elbows in sand, I’d take the watch off first.
I’d note that you’d probably be fine moving the watch to your ankle while digging, as an easy way to not lose it. Of course, this assumes that your kids won’t be burying you, and that you’ll move it back to your wrist before plunging your feet into the sand.
I would not go full ten-year-old-in-the-sand with the watch. Maybe with a future version that doesn’t have a digital crown that physically moves, but not this version.
I do, however, fully intend to take my Ultra to the beach and get knocked over by a great many waves.
