I love my G-Shock watch. Practically invincible, can drop it from a building or go swimming with it, charges by solar panels and never dies, syncs with atomic clock towers by radio waves (no need for NTP!). I can set alarms, timers, stopwatches across timezones. It has dates stored locally until 2099 and it just cost $100. Smart watches may be more convenient for you, but imo the Casio is a better value and won’t ever need to be replaced within 5 years because it doesn’t get software updates
