Based off of my favorite watchface for an old garmin (https://apps.garmin.com/en-US/apps/11c2548e-8878-497f-809b-ea640e54ca43). Uses Open-Meteo for weather, displays battery %, Calories, Steps, Distance (configurable stride), and either HR or Sleep time depending on watch. 
Shows seconds for 60 seconds after backlight turns on, then hides them to save battery.
