This watch powers itself using the movement of your arms.

The watch has dual sapphire crystals with one of the digital watch face and the other over the rotor for that little micro-generator that keeps the thing powered up. The watch stays powered for 45 days so it won’t go dead overnight on you. The watch features LED backlight, dual time zones, alarms, and a perpetual calendar.

The watch also has some sort of OS behind the scenes. That would mean that updates might come to add other functionalities to the watch as well. It’s cool looking for a digital watch. The big downside to this watch is the price; it sells for $5,500. The black watch is a limited edition. A silver version is available as well for $5,250. via Slash Gear
