The Breguet 502DR is a tourbillon movement used in the Classique Tourbillon series. The tourbillon cage completes one revolution per minute and uses Breguet's signature parachute shock absorber on the balance staff. Finishing includes hand-chamfered bridges, Côtes de Breguet on the plate, and blued screws. It represents the continuity of Abraham-Louis Breguet's original tourbillon patent applied to modern manufacture standards.
