You could easily drop 15-20 grand (or more) for a fancy Rolex wristwatch that all your friends will probably think is a knock-off anyway. But you could also spend that same portion of your inheritance on a super-cool timepiece from former British specialty-car builder Devon Motor Works (now called Devonworks) and be really different. For example, the Tread 2 uses four miniature motors attached to a series of drive belts that control the hour, minute and second readouts. All of the action, which is visible through the watch’s bulletproof-glass casing, is controlled by a battery-powered microprocessor. Tread watches start in the $12,500 range.
