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.

Combine art and spirituality. Create a new masterpiece that aims to pay homage to Japanese culture. Richard Mille presents the RM 47 Tourbillon, the culmination of nearly four years of in-depth thinking and design work. This is a new art watch with an extremely compact movement designed to make room inside the case for a completely handcrafted stylized samurai armor. The model was born out of a friendly dialogue between Richard Mille and Fernando Alonso, two-time Formula 1 world champion and partner of the brand, passionate about traditional Japanese arts and samurai codes of conduct.
