5 Most Expensive Watches That Cost More Than Your House
4. Breguet Grande Complication Marie Antoinette – $30 Million

Commissioned in 1783 for Queen Marie Antoinette herself, this watch took decades to complete—and she never even saw it finished . The original was stolen in 1983 and later recovered, and a modern recreation took another four years to build. Packed with every complication known at the time—thermometer, perpetual calendar, minute repeater—it’s essentially 18th-century engineering pushed to its absolute limit. The queen was executed before it was done, but the watch outlived her by centuries.
