There are a lot more of these around than you might expect! Setting is as simple as possible, requiring no rare and expensive complication.
But the second independent dial face can be used as a kind of chrono!!
Set it to 12:00 and is will display the elapsed time for the next twelve hours. Or if you are, say, cooking a roast that takes forty minutes, set it to 11:20 and it will count down to twelve! I really like that idea.
Want to see how long the day is? Get up at sunrise and set it to 12:00 then wait until sunset. Or you happen to know how much daylight is available (for a trek) and want to make it back home in time before it gets dark, using the "countdown function".
With a pocket sundial you could even set it to mean or even true solar time for a particular day and avoid getting precooked - or even roasted - on the beach with the sun blazing overhead, when "normal" time tells you that it is already afternoon and safe in the sun.
Or just keep it set for the same time to experience the symmetry, like identical twins who react in the same way. Even there you have the choice of wearing the Resonance on the left or on the right wrist, with just enough from the cuff (discretely) exposed to be able read off the time - or set the dials anyway you prefer, according to left and right.
Anyone have more ideas? I think your question has already been answered: two independent watches in one, resonating with each other with the same accuracy, no matter what hours and minutes they happen to display.
Sorry, but I didn't know where to put these thoughts on the second "time zone" without starting a thread. They came faster than I can type!
