The Cintrée Curvex™ Double Retrograde Hour revolutionizes traditional time reading with its distinctive dual retrograde displays. The upper arc of the dial tracks daytime hours from 6 AM to 6 PM, while the lower arc handles nighttime hours from 6 PM to 6 AM. This innovative design provides a clear, sophisticated way to differentiate between day and night, showcasing Franck Muller’s commitment to unique and functional timekeeping.
