The TSAR BOMBA Reactor TB8213 won the French Design Award and the Gold Muse Award for its unconventional way of telling time. Instead of traditional hands, the upper dial shows the minutes and the center dial shows the seconds. On the lower display, the hour is the number the hand points to plus the number in the central window. The TSAR BOMBA interchangeable system lets you swap the strap, bezel and crown without tools.
