Whatever you get, test the alarm function to make sure it will wake you up. I have a lower end g shock and the alarm is only two short beeps and that’s it. It would never wake me up.
I had a nicer g shock, I think a rangeMan, and it was awesome. A little thicker than I’d prefer but it was solar, atomic and the alarm was great. It was a 3 sensor deal, too. Lost that at my buddies wedding after a week in the woods. Whoops.
