Don't look at the Harry Winston Opus XIII Watch if you easily get vertigo. The watch face has a sliding trap door, eleven spinning triangles as hour hands, and fifty-nine minute hands. to be completely honest looking at the watch face I can't even tell what time it is (my guess is 10:05?).
The watch was developed in collaboration with Ludovic Ballouard and features a 44.25 mm case of 18K white gold, a hand sewn black alligator leather strap, a sapphire crystal front and back, a 35-hour power reserve, and is water resistant to 30-meters. No idea on price yet, but considering there are only going to be 130 units made I assume they will be expensive.
