Watch that uses compressed air to power the system

Air-Powered Watches

This watch has the potential to outlast anybody who owns it. The Urwerk UR 202 Turbine Automatic uses compressed air to regulate how it is wound. The Urwerk's "Revolving Satellite Complication" face is patented and relies on fluid dynamics, which are controlled by air friction to cushion the winding system. Since it's the winding that wears out a watch, this makes it virtually impossible to wreck the Urwerk.
