Timecrafters, the watch show that takes over Manhattan's Park Avenue Armory every spring, is a celebration of luxury as a product of engineering. There were pounds of rose gold and gems on site, but, for a certain type of watch enthusiast, the craftsmen building complications on the spot were the bigger draw. We picked five standouts from the distinctly American show, where practical beauty trumped ostentation.
Jaeger-LeCoultre Duomètre à Sphérotourbillon
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]
