The mechanisms of the triple-complication Blancpain Le Brassus Carrousel Minute Repeater Flyback Chronograph (www.blancpain.com) are built alongside one another—or “integrated,” in watchmaking parlance—and visible through an open-worked dial. The watch is the latest installment in Blancpain’s series of timepieces featuring renovated versions of its complicated movements. The company has been releasing these watches on an annual basis for the past several years. The carrousel, a tourbillon-like escapement with extra gearing, and the flyback chronograph have become the brand’s signature mechanisms in recent years. The repeater features distinctive engraved hammers and produces a clear sound. The watch is priced at $449,600.
