I owned one a few years ago,sold it,and immediately regretted selling. I finally got around to replacing it and couldn't be happier.
The watch is a beast!! Big and thick and meant to be worn in the water or anywhere else a mere mortal watch might fail. You cannot hurt this watch. It's my car washing,fishing,beach and camping watch. Also fun to wear just around the house. In the watch collecting world it's an iconic model affectionately referred to as the "eco-zilla"
