The LUC calibre 1TRM is manually wound fitted with a flying tourbilon that features Chopard’s distinctive three-armed tourbillon cage. And like all Chopard tourbillons the balance wheel is the proprietary Variner (VARiable INErtia) balance. While I appreciate the quality of finish and movement construction of the Engine One, as I do with all of the upper-end Chopard LUC watches, the design strikes me as a cross between a Daniel Roth and Richard Mille.
Nevertheless, the Engine One is fairly priced and one of the more interesting options in the crowded field of tourbillons. It is a limited edition of 150 pieces. – SJX
