Not sure he researched his options well enough. The Garmin watches that use a MIP display only require a charge about once a month, probably even less if you turn off the Bluetooth, which gives him the other thing he wants, no distracting messages relayed from the phone. Battery life is potentially even longer for the models with solar charging.

I also find the reasoning in "Why track your sleep at all? If you’ve had a crap night, you’ll wake up tired." weird. That's the equivalent of saying "Why track your blood pressure at all? If you've had a problem with high blood pressure, you'll wake up with a stroke." Not that the sleep tracking on smartwatches seems to be worth much but I just don't agree with the logic.

"a few seconds a day" why is that accuracy even needed? Sure, if you work with computers (that can tell time too), or are a mariner without GPS. But otherwise, just live with it.
