A watch face inspired by the "Celestial Whimsy" aesthetic, where the clock hands have been replaced with a live visualization of the sun and moon rising and setting.

At solar noon, the sun will sit at the exact top center of the watch face, and it will sit at the bottom center at exactly solar midnight. The same is true for the moon, which will reach the top/bottom of the watch face during tidal noon and midnight. The current moon phase is also calculated and displayed live. The sunset/sunrise times (as well as relative amount of daylight for the current day) are visualized by sliding the color bars up and down the clock dial.

The watch face reads your current GPS location from your phone's Pebble app when it starts up. But, after that, the calculation runs entirely on the watch, and it stores the most recent location in persistent storage, so it should continue to work even if your Bluetooth connection drops.
