I had no idea the battery life on most smart watches is so bad that "24 hours of screen on battery life" is something to brag about. The apple watch is no better.
My Garmin Forerunner 945 (a running focused smart watch), more than two years old at this point, gets nearly two weeks of battery life on a single charge, and it's got an always-on screen as well.

Quick edit:
Even the latest Forerunner 965, which has an AMOLED touch screen, gets 7 days of battery life in display-always-on mode, and 3 weeks in default mode (display turns off)^1
