I haven't used a clock in years that I need to manually reset. Older people don't seem to realize clocks on phones and other devices reset automatically.
I'm 42 years old, and I have a fairly new watch, a Casio WS-1300H. Made in like 2022 I think. It's not smart, if anything it's just as dumb as a watch from 30 years ago.
But it runs on a button cell battery, said to have a battery life of like 10 years, as long as you don't use the backlight too often.
Yes, I had to manually change the option for Daylight Savings Time, but they make it really easy to do, it's all in the manual.
