With a 42mm matte black ceramic case and red accents, Chopard's versatile new piece can be worn with jeans and a t-shirt or a Tom Ford tuxedo. The watch's ultra-high frequency escapement is so sensitive that the brand claims the caliber is half as likely to experience deviations caused by external factors. And thanks to weight saved by silicon pieces, it still manages a respectable 60-hour power reserve. We are, in short, talking about the ultimate motion-powered metronome. Take note of the sapphire porthole in the back that exposes the beating heart of the balance wheel. [$20,820, edition of 250; chopard.com]
