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. Like all other iOS apps, Emerald Geneva cannot set the devices internal clock.)
