Legend has it that this watch was initially commissioned for the iconic French queen and fan of life’s finest things, Marie Antoinette, by one of her lovers. Crafting this exceptional piece took around 40 years, and she was executed before the work was complete—only adding to the romance and enigma of this historic timepiece. 

Encased in gold, it includes every complication that existed at the time, including a perpetual calendar and thermometer. After being stolen in the late 1900s, the watch is now safely locked away in the L.A. Mayer museum but is available for purchase for those with $30 million.
