Also, in regards to the GP, great technology, but I would love to see it (a) in a simpler watch, and (b) not "tourbillonified" (as the Hodinkee article mentioned). I see no reason why this technology cannot become 'mainstream.' I would love to see it in their more classical watches. Plus, you get to see the beauty of it without the display back, which is nice. All in all, great work by GP. I look forward to seeing the actual tests.
