Description
These models of high-end mechanical watch faces 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.
NOTE: This app (Emerald Chronometer) is optimized for the iPhone and iPod touch. Please also see Emerald Chronometer HD, a separate product optimized for the iPad.
Astronomy features:
- Highly accurate data from 4000 BCE to 2800 CE
- Times of rise and set for the Sun, the Moon, and the 5 classical planets
- 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
- "Compass functions" show the elevation and azimuth of the Sun, the Moon, and the 5 planets
- The Equation of Time, solar time and sidereal time
- Eclipse predictor (lunar node indicators and separation indicator)
- User settable geographic location and timezone using an 80,000 city database
- A unique face showing the rise and set times of all 5 classical planets plus the Sun and the Moon at once
Clock features:
- Day/date/month/year indicators, using mechanical wheels
- Local and UTC time
- Chronograph (stopwatch) with split timer, 1/10 sec accuracy
- Alarm clock and interval timer; notifications are delivered in iOS 4 if the app is not running**
- World-time watch with 24-city ring on one side and 4 subdials on the other
- Calendar watch with rotating wheels showing a full month at a time
- Most watches with 1/5 sec or 1/10 sec precision
- Synchronized with standard atomic clocks via NTP
There are 16 watches in all, with 27 total watch faces (including front and back sides).
A setting is available to allow the display to stay on only when plugged in.
Play with the watches by tapping on the crown and moving the hands, or press and hold on a date window to zoom through time to see the effect on the heavens. Then just use them to show you when it's time for a break.
A complete description of each application feature can be found in the built-in Help screens and on the Emerald Sequoia LLC Web Site, which also includes a demo movie. A developer's blog may also be found at http://emeraldsequoia.com/esblog/ .
If you are having any trouble with the application whatsoever, please see our FAQ on the support page listed below and then contact us through that page if your problem is not resolved. We take pride in responding promptly to all support email requests.
**NTP accuracy is not guaranteed for alarm delivery if the app is not running. (NTP requires Internet access. Like all apps Emerald Chronometer can not change the device's internal clock.)

Customer Reviews
Elegantly Superb
Emerald Chronometer is superb. Elegant graphics with excellent functionality. It is a companion in my observatory for initializing the telescope mount and for timing exposures. It elegantly and efficiently shows things of daily interest: day/night in different locations around the world, local daylight savings time rules, UTC, the three twilight periods, and lunar and solar locations along the ecliptic. The planet locator is also very useful. It is even an elegant timer for brewing coffee & tea!
This is the elegant go-to app for good time accuracy via NTP - suitable for reference star sightings. The network time protocol provides an estimated uncertainty of the time.
This display is what should be on the Apple Watch.
A most incredible set of watches
A very long time ago, I wrote, "One day I hope to see a Kickstarter campaign to build a physical smart watch that lets me carry Emerald Chronometer on my wrist. This app really belongs where I can view it all the time.”
Well, the Apple Watch is here and I hope that Bill and Steve can shoehorn some of the functionality into the watch. I can guarantee you that it would be the best app available!
fascinating
I don't have a real need for this app, but I'm fascinated with time, and this app is appealing to me! I've learned quite a lot just from reading about some of the different watches included, and it has proven entertaining and enlightening!
For example, Firenze. Once home to Galileo! And this particular chronometer has an orrery. I also have a fascination woth orreries, so it was an amazing surprise to find one in this app!
