ENDURANCE Watch Face for Android Wear OS is a beautiful, minimalistic and highly customizable watch face for Android Wear OS. It will display your current time, date, and day of the week. In addition, it will display the current weather and the phase of the moon. It will work on any Android Wear watch, even those that have a different design.

You can customize the time format (12h or 24h), and change the color of the watch face, hour hand, minute hand, and the second hand. You can also add a background image and change the style of the font used.
