Perpetual Calendar Movements

Our interpretations of the challenging perpetual calendar movement are as creative as they are functional. The RD1429 movement is a gorgeous case in point: it boasts a unique in-line aperture display and offers a natural, legible alignment of the day, date, and month. This movement’s large date aperture lends even more clarity and simplicity—the complete functionality is delicately and seamlessly managed, eliminating the need for any date correction before 2100.
