Stolen: 200 clocks and watches, including the "Marie-Antoinette" made by Abraham-Louis Breguet
Location: Jerusalem, Isreal
Year: April 1983
Worth: $30 Million

Abraham-Louis Breguet's "Marie-Antoinette" clock is worth a cool million, and it was only a small part of this epic heist at the La Mayer Institute for Islamic Art. Authorities were convinced that the work was carried out by a half dozen or so men, suggested by the tools, food, and bottles left behind. Turns out it was the work of one man, a notorious Israeli bank robber, who confessed the theft to his wife while he was on his deathbed. The timepieces were later found scattered throughout Europe and Asia.
