    Vacheron Constantin’s sculptors were inspired by the tone of nature and the elegant lines of the Eiffel Tower. The complexity of decorative patterns and the exquisiteness of functional operation are another important feature of the movement, which makes it a masterpiece in skeleton models. The dial design needs to allow people to see the perfect craftsmanship of the hollowed-out movement and to read the display of the perpetual calendar function clearly.

    In order to achieve the above goals, Vacheron Constantin uses a transparent sapphire crystal dial, plus a silver-treated outer ring combined with the hour and minute scales. Therefore, through the dial, the perpetual calendar display becomes larger and clearer. The moon phase display also makes full use of the transparent effect and is interpreted by double-glazed matte glass.
