The Aston Martin Rapide might just have the most expensive key in the world, fortunately it does more than just open the car – it’s also a watch, sorry, chronograph.

The AMVOX2 Rapide Transponder heralds the second generation of the revolutionary creation that sealed the ties between the Grande Maison from the Vallée de Joux and the legendary British luxury sports car manufacturer.
Released several months ago, it is the first mechanical watch developed with the ability to control access into a luxury sports car by means of a built-in micro transmitter system serves to lock and unlock the Aston Martin DBS car, while maintaining the key functions of the famous vertical-trigger mechanism equipping the pushpiece-free chronograph.

If I had enough money for an Aston Martin, I would probably cough up for the super-expensive watch-key.
