Sometimes my Ultra 2 seems a little big and clunky, but I still wear it all day.
The main thing, I guess, is that even though it's big it's still a lot smaller and easier to manage than an iPhone. I can rely on the GPS and cellular systems to still get location right, and calls and messages work...although sometimes a little slowly.
I only take it off to give it a little charge, once or twice/day when I'm not moving much.
The Watch will start my Ford Mach-E GT if I want, if I'm late and want it ready before I get home. Weather. Timers. Activity. Sleep tracking.
The other day it warned me that my bpm had dropped to 40-41 for about ten minutes at night.
I'm 76 and have had one stroke but I still try to stay active, and the Watch called the sheriff when I had an accident on a trail.
So I'm basically stuck with the Watch Ultra 2, but don't mind much.
I hope the original poster is able to get things sorted a little better.
