Emerald Geneva

This model of a complex mechanical watch contains many of the most complex "complications" found in real watches, plus refinements found nowhere else. The displays maintain the look and feel of a real mechanical watch, but with considerably more complexity than possible in real mechanicals and with the time and location accuracy of a modern computer.

Free for a limited time! Geneva is just one of 14 watches included in our other apps, Emerald Chronometer and Emerald Chronometer HD.

Play with it 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 it 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 of Emerald Chronometer.

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 time synchronization requires network access. Like all other iOS apps, Emerald Geneva cannot set the device's internal clock.)
