The Palatial Flying Tourbillion Minute Repeater unveils its mechanical magic through a translucent blue, red or green mineral crystal. The entire minute repeater mechanism, which is usually hidden away from view under the dial, is visible here -press the slide which arms and activates the repeater, and one will hear the hours, quarter hours, and minutes rung on two cathedral gongs. All the charm of an haute horlogerie timepiece and musical instruments are combined to create an incomparable sophisticated time-keeping choreography of a complex system of racks, snails, and levers that bring to life the song of time.
