Combines fusée-and-chain transmission with one-minute tourbillon - two of the most effective complications for rate accuracy. Features patented stop-seconds mechanism allowing the tourbillon and entire movement to be stopped and restarted to one-second accuracy. The intricate 636-part chain unwinds from the mainspring barrel onto the fusée, working like an infinitely variable gearbox to equalize the waning force of the mainspring.
