For some reason, watch designs that are able to fiddle with cars are always interesting, and the Silver Arrow Concept draws its inspiration from the Mercedes-Benz AMG SLS. The design incorporates a whirl, a power reserve, and a tachometer with its needle’s three star shape reflecting the Mercedes brand. The more interesting feature of this watch is that it features Open and Close buttons around the ring, which allows you to lock and unlock the car remotely, which is something we’ve always wanted to do with our watch.
