I came here to say this. I had abandoned smartwatches entirely and gone back to mechanical watches because smartwatches just did too much and the small utility I got from them (i.e. health) came with the tradeoff that they had to be charged every couple of days. I ended up trying the Garmin Instinct and it has been exactly what I was looking for. I turn off all notifications and just use it for the data it gives me and for the fitness tracking.
