This watch winder will cost you a small fortune. The reason? It uses some engineering secrets from NASA's zero gravity astronaut trainers - aka aerotrims. The watch winder will spin your timepiece in all directions to keep it wound when not being worn.

But for a price tag of $18,000, it's definitely cheaper to wind it yourself. Still, a beauty to look at for sure.[Hammacher Schlemmer via Coolest Gadgets]
