Limited edition of 37 pieces worldwide. Available now. In stock!! The Classic Perpetual Calendar Manufacture in gold and onyx. Upon its launch in 2016, Frederique Constant’s Classic Perpetual Calendar Manufacture made watchmaking history by becoming the most affordable perpetual calendar on the market. Today, the brand once again pushes the boundaries by improving not only the quality and finish of its components but also the technical specifications of its movement. The model is available in an 18-karat yellow gold version, a treatment the Manufacture reserves for its most prestigious collections. The dial, meanwhile, is crafted from black onyx, offering striking contrast and timeless elegance. At the heart of this watch is the new in-house caliber FC-776, the 34th movement developed internally by the Geneva-based watchmaker, whose power reserve has been increased from 38 to 72 hours—that is, three full days.
