- The house that invented the complication
Breguet patented the tourbillon on 7 Messidor An 9, 26 June 1801, and has never stopped saying so: the date is written on the dial. The 5367 is the modern argument for the house, an extra-flat self-winding tourbillon under a grand feu enamel dial, with eighty hours in the barrel. You are buying the invention itself, from the name that owns the story outright, and paying a two-century provenance premium for it.
