The watch that took 44 years to finish

In short: Imagine a commission so complex it outlived its owner, its patron, and the very revolution that ended their era. This is the story of the Marie-Antoinette pocket watch, a masterpiece of horological endurance that bridged the gap between the French monarchy and modern engineering.

In 1783, the Swedish count Axel Von Fersen commissioned a watch for Queen Marie Antoinette. He demanded a piece 'as spectacular as possible,' incorporating every watch complication known at the time. There was no deadline and no financial limit. The resulting masterpiece, the Breguet No.160, was designed by Abraham-Louis Breguet, a pioneer who founded his workshop in Paris in 1775. Breguet was a polymath who studied under masters like Ferdinand Berthoud and Jean-Antoine Lépine, eventually inventing foundational technologies like the self-winding watch in 1780 and the tourbillon in 1801.

The complexity of the No.160 was so immense that it was not finished until 1827—34 years after the Queen's death during the French Revolution and four years after Breguet's own passing. It took a total of 44 years to complete. The watch even survived a period of displacement, spending time in the Museum for Islamic Art in Jerusalem before being stolen in 1983 and finally recovered in 2007.

Breguet's legacy is defined by these 'grand complications' and technical firsts, including the world's first wristwatch in 1810 and the first perpetual calendar movement for wristwatches in 1929. While the brand is now a subsidiary of the Swatch Group, it maintains its status as a pinnacle of luxury, recognized by its distinct coin-edge cases, guilloché dials, and 'Breguet hands.' Its history is a lineage of elite patronage, counting clients from Napoleon Bonaparte to Winston Churchill.
