Thirteen Cool Things About the Most Complicated Watch Ever Made

In horology a “complication” is an additional function on a watch beyond timekeeping. The more complicated the watch, the more impressive the skill of the artisans and engineers who created it.

With 63 separate complications, Vacheron Constantin’s Les Cabinotiers Berkley Grand Complication, announced on April 9, is the most complicated watch on Earth, representing 11 years of development. Commissioned by the insurance billionaire William Berkley, it’s made from 2,877 components and weighs more than 2 pounds. Its price is undisclosed, though surely it’s in the millions.
