Emerald Chronometer
Version 2.1
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.
