Imagine a watch that is wound using compressed air; the UR-202 Hammerhead Automatic from Urwerk that has a unique winding system that's regulated using compressed air! The watch uses miniature twin turbines to control the rate of automatic winding and the level of air compression can be controlled using a 3-position selector switch. What even more interesting is the way the watch tells the time; it uses an elegant series of rotating hour blocks built around hands. They adjust their length to mark the minutes. No word on pricing as yet, but check out the cool video.
