Great example of a beautiful designed and crafted complicated timepiece.
A little history and background:
Introduced in 2001, the GST Perpetual Calendar from IWC is mechanically programmed until the year 2499 (The Patent for this special programming mechanism is held by IWC Schaffhausen )
This eternal timepiece not only handles current and future time but also comes with the most popular additional function of the age: a classical mechanical chronograph that provides aggregate timing of any period between one eighth of a second and 12 hours.
Calendar is powered and controlled completely independently by the main automatic movement and the extra day in leap years is likewise handled without any intervention from the owner.
This also applies to the phase of the moon display, one of the most accurate in existence. After 122 years in action, it will be just one day out, and the necessary tiny adjustment can be made by a watchmaker.
