We first told you about the QuantumGravity tourbillion back in January, but now this physics-defying watch is ready for consumption by 10 very, very rich individuals with messed up priorities.

We already knew that the Concord C1 QuantumGravity could counteract the forces of gravity thanks to 18th century technology that involves the escapement and balance wheel being mounted inside a rotating cage—but it appears that the mechanism also includes a "liquid featuring green phosphorescent nanoparticles" encased inside a vertical tube. Apparently, this fluid is used to indicate the power levels remaining in the 3-day reserve. To be perfectly honest, the press release describing the watch and its mechanisms is is pretty damn convoluted (unless you are a master watchmaker), but it will undoubtedly prove popular when it is unveiled at the Baselworld 2009 show next week.
