Found these over at watchismo.com. Neat watches. Not something I see myself purchasing, but admire the engineering that has to go into making one of these creations. More info from watchismo:
 

MADE IN THE USA

The Devon Tread watch is arguably the most cutting edge watch made today, a timepiece of striking visuals and technology.  The Tread 1 Watch features four internal 2-micron thin belts that spin within the case to display the time.  It’s powered by a lithium polymer rechargeable cell that is charged by wireless induction.  This electric system runs the belts that are kept in tune with an optical technology.  Add that all up, and you have one of the most technically advanced, visually stunning watches ever made.  The Devon Works Tread 1 Watch was designed by a California aerospace company, a group that is quite comfortable with fitting square pegs through round holes.  This watch is a prime example of their technical prowess.

Operating out of California, DEVON is the only American watch company using its own proprietary movement. In late 2010, the Tread 1 was nominated for the Gran Prix d’Horlogerie de Genéve in the category of Design and Concept Watch – the first American watch brand ever to receive this laudable recognition.

Led by founder Scott Devon and headquartered in Los Angeles, California, Devon Works, LLC is a design lab dedicated to creating innovative luxury products that exemplify the American spirit.

I saw one in the flesh last year. Although very cool, the proportions were ridiculous. I hope as they perfect and evolve the design they are able to shrink the watch down to something appropriate for the under 7 foot tall set.

Different indeed...I'll have to pass.

Definitely different. Has to be an extremely complex design.
