IWC Da Vinci Perpetual Calendar Chronograph Owner Review : Phenomenal, admirable and fascinating

First encounter with this magnificent watch more than 20 years ago but unaffordable for me at that time, and later found on the web. This perpetual calendar is just magical because it is programmed until 2499 without any adjustment necessary except to turn the crown, and this thanks to Kurt Klaus its brilliant inventor! second, chrono, hour, day, month, year and moon phase advance as if by magic which makes it the watch of future generations par excellence. This is why I engraved the initial of my father's first name at 11 o'clock and of my son at 1 o'clock to whom it will belong one day.
