This is a cool idea. I hadn't really toyed with the idea of my watch living anywhere but my wrist.
Like the GP, I have to remove mine a lot for computer sessions, as a heavy keyboard user.
I'm really fatigued by all the stuff I have to carry each day. I think the watch is often the best bang for the buck. Pretty small, rarely in the way, lots of utility.
I don't care about the health tracking, so the ankle isn't an option, but I'm going to think about other ways I can use my (Galaxy) watch.
Nothing--duplicate functionality on my wrist. That's useful for me a lot: motorcycling, fishing, kayaking when I want my phone in a dry bag, silent notifications.
The ease of accessing a voice assistant is nice--I double click a watch button to set reminders/timers/alarms. It's a shame the VA is bixby, but mostly it gets the job done.
You've answered far more of my questions than you know! I appreciate the answer - and am now contemplating a smart watch. I'd want something tiny, and waterproof, with an analogue face.
I like to wear my watch a few cm higher up my arm, so that the metal band doesn’t scratch my laptop.
If you want features that need skin contact, you could keep a nice watch as a pocket watch, and then wear a cheap fitness band on your ankle.
