I've got an automatic Speedy as opposed to the manual wind. So far I've found it to be pretty tough camping (in a tent), and on the lake (100m rated). I was googling to see if anyone else used theirs outdoors as well, and found this thread. I don't feel so bad taking mine out biking tomorrow, lol. Seems a shame to spend so much money on a watch, just to leave it at home when I do the fun stuff. The only thing I think I might leave it behind for is the gym. So far I've used an Apple Watch for that, but it's not really necessary. I know what I'm doing, I don't need a watch to track it for me.
