In 1782, watchmaker Abraham Louis Breguet began his work on a gold pocket watch for Marie Antoinette. The Breguet No. 160, as it was formally named, represents the epitome of watchmaking craftsmanship. Handcrafted out of gold and rock crystal, it was completed in 1827, 4 years after Breguet’s Death.
Stolen in 1983, fromL.A. Mayer Institute for Islamic Art in Jerusalem by renown master-thief Na’aman Diller, along with 39 other precious watches, it was finally recovered in 2007. It was last valued at $30 Million, in 2013. It stands as the rarest and most valuable watch in the world today.
