For Watch Connoisseurs BREGUET LA CLASSIQUE CHRONOMÉTRIE REF 7727 10HZ Breguet’s La Classique Chronométrie is widely regarded as the most precise mechanical watch of all time.

This watch is a tribute to this tradition, incorporating Breguet’s much lauded magnetic pivot that uses magnetism to set a new standard in accuracy and reliability (-1/+3 seconds a day). The gold exterior is equipped with silicon double balance-spring, pallet lever and escape wheel, with a power reserve of 60 hours. Price: $44,500
