Greubel Forsey's tagline is "the art of invention," and its iconoclastic architecture straddles the intersection of sculpture and engineering. But it's a very thin line on which to balance. While the brand's timepieces do have an avant-garde visual flair, they're always tempered by chronograph function, creating a gorgeous yet restrained tension between visual beauty and wearing purpose.

A Jacob & Co. masterpiece in a limited series, based on Bugatti's performance cars. Its unusual design is a tribute to the Chiron Sport "110 years BUGATTI" limited series. The turquoise dial proudly displays the Bugatti logo, while the power reserve indicator has been renamed "Fuel". Only 39 pieces of this stunning timepiece will be produced and numbered.
