    Congratulations with this icon and I guess it is your birthday presen!

    this is a real masterpiece and the only IWC watch of which the 'sun hand'
    makes one revolution in one year.by a direct reduction, powered by the wheel
    train. Zodiacs were normally made at large size for turret clocks Some
    figures:

    The sun hand moves 0.986 degrees per year or 0.392 mm per day at the tip. If
    one multplies 0.986 x 365, one gets 359.890 degrees, approaching 360 degrees
    by 0.11 degrees per year. If the sun hand would move one thousandth of a
    degree more per day, the figure would be 0.987 x 365 is 360.255 degrees per
    year, making the watch slightly more inaccurate.For a leap year the watch is
    corrected over the crown.

    The watch was realised by Reinard Meis - a famous author of watch books- and
    Gunther Blumlein, IWC's CEO in 1980. They worked together with the
    Laboratoire Suisse de Recherche Horlogere to find a suitable shape of the
    wheels to achieve an optimal transmission between them. Very few 'Zodiacs'
    were made.
