De Grisogono Meccanico dG
Contrary to its appearance, the Meccanico dG has no digital components. Below the more conventional analog portion of the two-timezone watch is a numerical display driven by the intricate interplay of 651 strictly mechanical components. Numbers are formed by the motion of 23 cams, which are connected to gears and a synchronization system.
To prove it, the watch's back features a transparent dial plate that affords close scrutiny of the timepiece's inner workings. Billed as the world's most complicated watch, its creation marks the 50th birthday of the Geneva-based company De Grisogono.
The Meccanico dG comes in four styles (red gold, titanium-and-gold, titanium-and-platinum and titanium-and-rubber) and is waterproof to 100 feet. Although pricing information and availability are forthcoming, it won't be easy to claim one of the mere 177 produced.
