Celestial Ephemeris

Watchface
Description
A living astrolabe on your wrist. This watchface transforms your Pebble into a precision astronomical instrument, displaying real-time planetary positions around a zodiac wheel. At the center, the current moon phase fills the dial. The time floats over the lunar surface. Around the wheel, twelve zodiac signs mark the ecliptic. Planet symbols radiate outward with colored lines tracing back to their exact positions on the ring. Each line's color reveals the element of the sign that planet currently occupies: orange for Fire, green for Earth, yellow for Air, blue for Water. When a planet goes retrograde, it turns red. The brightness of each planet symbol encodes its essential dignity — planets in their domicile or exaltation shine bright, while those in detriment or fall dim to a whisper. A subtle dot appears when the Sun is about to cross into a new sign. Behind everything, 75 real stars from the Hipparcos catalog sit at their true ecliptic coordinates - Sirius, Vega, Arcturus, and dozens more form an accurate stellar backdrop. All positions are computed on-watch using JPL Keplerian orbital elements - no phone connection needed. Battery-optimized: the Sun and Moon update every minute, inner planets every 5, outer planets every 10, with retrograde checks every half hour. Tracks: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, and the North Node.
