Legendary horologist and founder of luxury watch company Breguet, Abraham-Louis Breguet made timekeeping history in 1801 with the invention of a much-needed, but highly complex watch mechanism. Seeing the adverse effect gravity had on reliable timekeeping, he created the tourbillon— an escapement housed within a mobile carriage that performs a complete rotation every couple of minutes. Basically, the regular repetition of the tourbillon’s variations offsets those made by gravity. It was a tough assignment for Bregeut to pull off, as it requires a certain durability while nonetheless maintaining its light weight.
