Emerald Chronometer for iOS
Version 3.9
Emerald Chronometer® is an iPhone™ application that models high-end mechanical watches.
These models contain many of the most complex "complications" found in real watches, plus refinements found nowhere else. All displays maintain the look and feel of real mechanical objects, but with the time and location accuracy of the iPhone.
Clock Features:
- Local, UTC time
- Day/date/month/year indicators, using mechanical wheels
- World-time watch with 24-city ring on one side and 4 subdials on the other
- Chronograph (stopwatch) with split timer
- Alarm clock and interval timer
- Most watches with 1/5 sec or 1/10 sec precision
- Synchronized with standard atomic clocks via NTP
Astronomy Features:
- Highly accurate data from 4000 BCE to 2800 CE
- Rise and set times for the Sun, the Moon and the 5 classical planets including a unique face showing the rise and set times of all 5 classical planets plus the Sun and the Moon at once
- The correct shape and orientation of the Moon in all phases but still using a mechanical display
- Relative positions of the Sun, Moon, 6 planets and the constellations of the zodiac
- Times of the solstices, equinoxes and apsides; position of the Earth's terminator
- Eclipse predictor (lunar node indicators and separation indicator)
- Relative positions of the Sun, Moon and the constellations of the zodiac
- "Compass functions" show the elevation and azimuth of the Sun, the Moon and 5 planets; twilight times
- User settable geographic location and timezone using an 80,000 city database
- The Equation of Time, solar time and sidereal time
