Luxury watch maker TAG Heuer has a serous passion for high-end car, and their latest partnership is with American super EV maker, the Tesla.

At this year’s Geneva Motor Show they came up with a special edition Tesla Roadster celebrating the Swiss brand’s 150th anniversary. It features a TAG Heuer Meridiist mobile phone as well as a one-fifth second Heuer Limited Edition Stopwatch. This Swiss-made timepiece with mechanical movement pays tribute to the 1860 founding of the company and evokes the mythic revival of the brand’s vintage stopwatches.

“TAG Heuer has a rich history and expertise with the world’s most prestigious racing teams — but this is the first ever partnership we’ve forged with an electric sports car company,” said Jean-Christophe Babin, President and CEO of TAG Heuer. “We believe that high-performance drivers are increasingly searching for products that are efficient, socially responsible and stylish. TAG Heuer and Tesla are two of the few companies already achieving these ideals today.”
