Leave it to Watchismo Times to find the perfect Halloween clock. Created in 1610, this mechanical Skull and Crossbones Clock was designed by Nicolaus Schmidt der Junger from Germany. The skull sits on two crossed bones and is mounted on a gilt brass tripod. One minute the skull appears to smile, then scream, then its jaw snaps shut, while the snakes, located in the eye sockets, take turns appearing and disappearing. Both are operated by cams that rotate twenty times an hour. Recently the antique was sold for $135,000. The clock is located in the top of the skull, just in case you wondered.
