I’ve had two garmins and a fat-bit. I found myself fiddling with them way too much in every facet of my life, checking that it was tracking everything and sending the data to my phone and making sure that the sweat and gunk wasn’t blocking the heart rate sensors. They would count steps and flights of stairs on washboard roads but wouldn’t always track while hiking. I found them more of a distraction and annoyance than a true help to my life, in field or otherwise. Plus it drove me nuts that I was paying over $500 for a watch that I had to replace every 18 months due to obsolescence. I already had a cell phone that did that, I didn’t need another device with the same weaknesses.
I’ve been wearing a G Shock for the last 3 years and I’ve never looked back. I have a couple different ones depending on the time of year or what I’m doing, but they all accomplish the same goal: telling the time so I can leave my phone in my pocket. They’re far more rugged than a smart watch, many of them are solar powered, they have models with heart rate monitors and altimeters and compasses, they’re 200m water resistant, and they’re cheaper to replace and don’t have the issue of obsolescence.
Sorry, not exactly what you asked for, but as a younger guy, even I got over the smart watch thing pretty fast. YMMV.
