The Story

For this watch, and for the first time ever, IWC has produced a case machined from 18-carat hard gold, a special variant of 5N gold. The sophisticated production process alters the alloy's microstructure, making hard gold significantly harder and around 5 to 10 times more wear-resistant than conventional 5N gold. The hard gold case and crown also create a beautiful contrast to the blue dial. The patented constant-force mechanism disconnects the escapement from the direct flow of energy transmitted through the wheel train and, second by second, increases the tension in a balance spring. The latter stores the energy temporarily before dispensing it in absolutely even impulses to the escape wheel. Together with the tourbillon, it guarantees an extraordinarily high level of precision. The IWC-manufactured 94805 calibre also features a perpetual moon phase display. The little prince stands on the moon. A 96-hour power reserve is stored in two barrels.
