Blancpain 56F9U

The Blancpain 56F9U is a manual-winding in-house movement featuring a grande complication that combines tourbillon, perpetual calendar, and split seconds chronograph. This highly complex movement represents one of the most sophisticated configurations in the Blancpain 56xx family. The combination of these three complications—particularly the split seconds chronograph paired with a perpetual calendar and tourbillon—is exceptionally rare in modern watchmaking. The movement was discontinued, with notable versions produced in precious metal cases.
