Description

Daylight has twelve hours. So does night. Their lengths change with the seasons and your location. Planetary Hours follows the traditional sequence of seven planetary rulers, with each new planetary day beginning at sunrise.

A wheel highlights the current hour. The center shows its planetary symbol and minutes remaining.

Enable location access for the Pebble phone app. It uses your phone's location to calculate sunrise and sunset, then saves the schedule on your watch. The face keeps working offline while that schedule lasts. Labels show whether the location is fresh, saved, or stale; an expired schedule asks you to reconnect. Polar day and polar night have their own status screens.

Coordinates stay on your phone. The face updates once a second on round and rectangular Pebbles, with a monochrome version for black-and-white screens.
