This is likely one of the most unusual (and expensive) auto-related products imaginable. Vulcan Innova has taken an actual BMW six-cylinder engine block, placed it on its end and converted it to a watch winder. Each of the six cylinders contains what’s called a rotating “stepper” motor attached to the piston that keeps the timepiece fully wound and ready for the wearer to strap on his or her wrist. The price for this one-of-a-kind watch winder is $25,000 (possibly even more expensive than an actual working BMW engine). Full details at
