I am such outdoors person, and mostly near, in or on the water. I only use mechanical watches for diving since they have to be open less the integrity is better. But this is a choice I am more comfortable with them plus a watch is also fashionable and is the only piece of jewelry I wear. And just because they're old fashion does not mean they're not complicated. I got watches with slide rule that allows me to do calculations way faster than a calculator since I just quickly rotate the bezel.
You can also use your watch to check you pulse just put some pressure on one of your veins and look at your watch and count, and not only you will see it but also feel it. You can also use your watch to find out where north is, this is an old boyscout trick.
I sail many times a year to Revillagigedo islands, Clipperton Island or halfway to hawaii for fishing and I am not dumb to rely on any of those digital gadgets. I always keep an analogue chronometer running while moving. I can confidently say that I had to rely on digital gadgetry I would be dead sine I had them fail on me more than once. Salt munches on circuit boards.
