But you're not going to places without reception... Think back of your army days, would the phone have worked out when out in the mountains or marching through the country? The Fenix is what disconnected tech looks like. It is its independence from both chargers and phones that "makes" it...I have Garmin Fenix that I used for running and cycling but I find the small size off-putting. There are way too many features and too few buttons to make it useful. the endless layers of menus is tiresome and maps are hard to read on a watch. Also, getting older and need readers and the small dial is hard to see for me at least.
Have shifted back to exercising with a mechanical watch with an easy-to-read face and will grab a cycling computer/GPS for my bikes next. I also wear cycling glasses with readers on them now.
I agree that smartwatches will not hold up over time. Just upgraded my iPhone 7Plus for a 12 Pro and it's like night and day. The old tech is useless once superseded.
