I got a smartwatch early in the pandemic because time stopped having any meaning and I started missing meetings all the time because I'd go do something not at my desk and then forget I had a meeting until I was super late. Also I had to set up reminders to do normal shit (eat lunch, walk dog, feed dog) because otherwise I'd forget. I tried doing it with reminders on my phone but then I'd set my phone down five feet away and forget.

Basically I have a smartwatch because my brain is broken and I need an electronic device strapped to me to nag me to behave like a human being. :(

Kind of similar situation, I am [sole] IT for a 24/7 business so I am never fully off-duty. Getting Teams notifications routed to my watch saves me from having to look at my phone as much as I otherwise probably would be. It actually reduces my overall phone time, which is a honestly a plus.

We do have a ticketing system, but execs like to ping me directly to look at the ticket they just submitted.
