I don’t disagree with you. If I hadn’t switched to the Epix when I did, I very likely would be wearing an AWU right now. The integration with all things Apple is just so good. But the thing I have come to realize is that many of the things I did on my AW5 were done when I already had my iPhone with me.Whilst the Epix line is great, of which I have one myself, it's aimed at a different market. The AWU is the best smartwatch, with some fitness features (albeit rapidly improving), the Epix is the best fitness watch, with some smart watch features.
There just so many everyday interactions with the AWU for me that are important...calendar interactions, email/ message replies, Siri, using as a remote for HomeKit/ AppleTV, interacting with reminders, authorising passkeys, unlocking my Mac, screening calls, answering calls when my phone is not nearby etc, etc.
The battery life on the AWU is now good enough to get through a couple of bigs days but I cannot foresee anybody not being able to take advantage on putting their watch on charge for 10m daily whilst they jump in a shower....certainly not the demographic the AWU is aimed at.
If your only concern is battery life, an old school Casio is the way to go.
So giving up the iPhone-like capabilities weren’t disruptive enough to my use case. I know I’m a bit odd here, but before I got the AW5, I had worn the same Seiko Automatic for 16+ years, and I almost never took it off. I wore it at night, I wore it in the shower, as well as when working on my cars. And of course I didn’t need to wind it, charge it or replace a battery for all those years. So the long battery life fits more with what I’ve been used to, as does the round form factor.
I’m not sure I could go back to a Casio or even something like my beloved Seiko Automatic (that my youngest son now wears daily), especially now that I’m tracking all the health, sleep and exercise metrics. I’m more likely to get the Epix Pro just to whittle down to charging just 12 times a year.
