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. Also, on OS's older than iOS 4, no third-party app may signal the user if the app is not running. NTP accuracy *is* maintained when the app is running with the device locked on all OS's. (NTP requires Internet access. Like all apps Emerald Chronometer can not change the device's internal clock.)

What's New in Version 3.9.1

- Fix black screen at startup on iOS 8 devices.
- Miscellaneous minor bugfixes.

Customer Reviews

Best of the best!

I don't know how I stumbled upon this app, but I'm really glad that I did! This is without a doubt the most beautiful, elegant app that I have on my phone. It doesn't hurt that it is also educational, informative, and eminently practical. But my advice is: get it for the superior design, and the features will recommend themselves.

Best Selection of Virtual Watches

This perhaps the oldest app that I still use on a regular basis and it’s wonderful that the dev has kept it updated all these years. Now that I own an Apple Watch, it would be wonderful to see the app on the real deal but I guess Apple hasn’t approved that capability yet.

A most incredible set of watches

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.
