Blancpain Tourbillon Carrousel – an engineering feat

Blancpain has designed a wristwatch that combines a tourbillon and a carrousel. This model has a flying tourbillon at 12 o’clock, a flying carrousel at 6 o’clock, and a date display at 3 o’clock. The two independent carriages are linked by a differential gear system, which transmits the average rate of both regulators to the time display. An external winding crown enables both barrels to be wound simultaneously and has a 7 day power reserve. The engine is the new hand-wound Calibre 2322 measuring 35.3 mm in diameter and 5.85 mm thick, composed of 379 parts including two new silicon balance-springs. The case is 44.60 mm wide and 11.94 mm thick.

Mechanically complicated to just be able to time the time and the date, this piece is an engineering wonder. Combining two gravity-error minimizing mechanisms shows the capability of the designers and engineers at Blancpain. I would get this piece just for the engineering feat. If I need accuracy, there are so many other alternatives much cheaper than this.

Below is a video from Blancpain detailing the differences between a tourbillon system and a carrousel system.
