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.)

Emerald Chronometer Reviews
Still loving it…
Bought this app a LONG time ago and still not tired of it.
Two little things:
- I would like a tropical zodiac option (but I appreciate it’s very much a niche interest).
- I’m now seeing faces for the Apple watch on the App Store. If Apple’s lifted its ban on third party faces, might it be possible now to give us an Apple Watch version? Yes, I know the developers have got day jobs and other priorities as well, but one can still hope…
All the same, this is still my favourite non-“Productivity” app on my phone by a long way. Highly recommended.
Simply beautiful
I love the Emerald Chronometer app - Mauna Kea is my favourite 'face'. Simply beautiful to look at with exquisite detailing - and constantly accurate.
Huge recommendation for anyone interested in the beauty and mechanics of time itself
Do you guys have any plans to release a version compatible with the Apple Watch?
Fantastic
Being a professional Horologist I can completely appreciate the work that has gone into making this app incredibly realistic and a perfect tool for me to use in setting customers timepieces. The "jerky" action of the second hand replicates the high beat of a mechanical watch and is not a fault of the app. Keep up the great work and thank you. It's worth every penny.
Beautiful app.
Jerky second hand on most of the watches, but a lovingly crafted collection of watches nonetheless.
The most beautiful app in the history of time 😉
My breath has been well and truly taken away. The chronometers are a visual delight and an astronomy enthusiast's dream, combining the joy of a real watch with the wonders of technology, for an incredibly low price for what you get. Getting to know these watches will lose me inside my own little private time zone for a long time to come. Wish my watchmaker and astronomer Dad was still here to enjoy it with me. Thank you developers-genius.
Stunning
The attention to detail is phenomenal.
Each watch has been meticulously crafted to covey a unique set of information messages on skilfully designed and animated timepieces.
The developers show excellent skill, capturing the design charm of classic horologes and animating them to precision.
Each watch has a comprehensive help screen that explains exactly what each dial represents and how it works.
Finally, I can have a watch ticking on sidereal time.
Great App, but iOS 8 flaws
I've loved the app since I've had it, but with the most recent iOS I just get a black screen. Hopefully an update is in the works.
Why?
I downloaded the new version using iTunes, only to find out that it won't run on my iOS devices because I can't update to ios 7. I had to restore the old version from a backup.
Only one star because this version drops support for anything older than iOS 7.
I adore this app.
Had it 12 hours. Can't believe what you have achieved it is a beautiful app. I've never said that before.
One request. Any plans for a tidal watch? Please.
Lovely attention to detail
Comprehensive features, beautifully designed, useful, and a delight to use. Excellent in-app help gives basic tutorials on the concepts used in the app. Finally, really cute details, like the way the second hand sweeps in front of luminous markings on the dials in night mode. Love it.
