5. Tread 1
Tread 1, created by Devon, is a reinvention of the humble watch with a patented system called Interwoven Time Belts. Operating out of California, DEVON is the only American watch company using its own proprietary movement. The Interwoven Time belts are based upon compact microstep motors which also provide the accuracy.
The watch is powered by a lithium polymer battery, and as it claimed by the creator, one charge will last couple of weeks. The five-piece case design is made from 316L, surgical-grade stainless steel, the hardest and most durable steel available in the world through advanced computer numerical control machining. The Tread 1 was nominated for the Gran Prix d’Horlogerie de Genéve in the category of Design and Concept Watch in 2010.
