A Fenix 5S+. A lucky garage sale find. I can't btw vouch for "fully debugged" on some of its fancier features. I mean map display? On such a tiny device? I'll just use my phone. But the basic sports stuff is rock solid.

fenix 5 - I have one too - within the 6+ years I have had mine - some people have replaced their Apple Watches 2 - 3 times

maybe for a light weight version I will go for a gshock
