The designers of the Ferrari have partnered up with Christophe & Co to develop a $189,000 hi-tech smart bracelet. The expensive wearable will grant you access to exclusive clubs across the world with a flick of the wrist and call to your “dedicated lifestyle manager”, who will presumably be able to advise you on your choice of suit or book tickets for a night at the opera. The device will be powered by kinetic energy generated by your movements.
