Yes, there was Harry Winston, with the Z6 ( from memory ) and a few years ago Patek with an astronomically priced one, but the Sonata is really apart. Uber alles!
That is the one I want. I think it is just the one yellow hand on the "regular" Silicium Sonata. I will have to find an old book and check, but I remember it had at least the yellow on/off hand.
