alt Hacker NewsI recently thought I could probably go back to a not-smart watch to not have to charge the watch all the time, but I don't want to deal with setting the time regularly either due to quartz drift and dst. So a bluetooth watch with two years of battery life doesn't sound like a bad idea really.
Even cheap quartz movements tend to drift by ±10 seconds per year, so you'd only really set it at dst. Maybe you're thinking about automatic watches which can drift by several seconds per day, and stop if you don't use it for 24/48/X amount hours. I have to set my automatic quite frequently
