The Breguet caliber 187M1 is an 18K gold handwound flying tourbillon movement with 23 jewels. It features a sapphire disc mechanism that creates the illusion of the tourbillon carriage floating freely beneath the dial. This movement marks Breguet's first flying tourbillon, housed in the limited edition Classique Tourbillon Sidéral 7255, of which 50 pieces were produced worldwide.
