One of the most innovative watches in history, Audemars Piguet’s Carbon Royal Oaks Tourbillon is a chronograph concept that amazes with its looks, technology and exquisiteness (see price below). Light, sturdy and obviously designed for those who can afford daily commuting by helicopter, the stylish watch has a forged carbon case, a hand-polished beveling, sides hand-drawn with a file, a matte surface, sapphire-blasted Carbon main plate and a hand-sewn alligator leather strap with large square scales. Close to perfection, this piece of art is worth a whopping $251,000. [via HypeBeast]
