Moon phase appears after sunset. the date window frame changes to yellow when the watch battery drops below 50% to red when it gets below 20%. normally it is a slightly brighter version of the user color choice. the day changes to red on Sunday just like a real watch. if the phone battery drops below 50% an indicator will appear below the date window in the same manner as the watch battery. Depending on your settings, the phone battery is monitored every 5 minutes or so. This is a new philosophy for my watch faces. trying to keep a clean, easy to read, uncluttered interface and only bring up information when it is needed. Annoyance fix: when the minute hand obscures the day and date. another copy appears on the left side of the dial disappearing again after it clears.
