Automotive enthusiast and designer Marko Petrovic’s Mercedes 320 Tourbillion watch is an homage to the Mercedes Benz type 320, a cabriolet first introduced in 1937. Inspired by the instrument cluster of the 320, the Tourbillion exhibits the same meticulous attention to detail and overall elegance still found in the brand today. Another nod to the automotive influence are hours and minutes shown as miles or kilometers in a racing scale. [Source]
