With two standalone movements, the Dual-Wing concept boasts individual energy sources that share a common regulating organ (one watch, two brains). While the Duomètre has long been a member of the JLC family, throw in the Sphérotourbillon element sprung from the new Hybris Artistica family and you have an additional, 3-D axis of rotation. It's gravity defying. This piece also has a hand-chiseled 18-carat white gold dial and two sapphire crystal domes that allow for pure transparency. Also of note: this is the first tourbillon that is adjustable to the second. [Price available upon request; www.jaeger-lecoultre.com]
