Yes, both for health tracking and because it's handy for notifications and calendar alerts. It's also a bit of a habit for time-keeping at this point.
Although I've found fancier, newer watches to be much worse for that. I replaced my old Garmin with a Samsung Smartwatch, since the corner broke off the Garmin, and the Samsung one had a metal frame that seemed more durable. However, the software is both worse and more fiddly than the garmin, which is itself worse than the software on the Pebble (RIP) I had a long time ago.
Yep, I wear an analogue watch every time I leave the house, and use it to know the time quickly. It also looks pretty, because I like my functional things to be decorative if they can be, but it's primarily functional.
I have a older style garmin (that's small and has an actual working watch face so it doesn't look like a fitness tracker). I mainly wear it for the tracking and stress/HRV tracking but the watch bit is handy when I'm in meetings or dealing with public transport or trying to put down the phone. I lived happily without a watch for many years but since I got it I've worn it all the time. If it broke I'd probably go without again until I found something I like that fits.
It's got a separate second hand that keeps falling off with bumps, and the rogue hand gets caught in the hour and minute hands. Fixable but doesn't seem to stick. And it makes me realise I barely ever look at it to tell the time, I just feel naked without it.
It was good back in the day, but I think it's just old now. It's been through a few battery replacements and had the glass replaced once. The Horse don't seem to make watches with separate second hands anymore, so I wonder if it was a known issue.
