The Big Pilot’s Watch Constant-Force Tourbillon Edition “Le Petit Prince” Story

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. In combination with the tourbillon, which offsets the influence of gravity on the watch's balance and spring, it serves to deliver extraordinarily high precision. Apart from the constant-force tourbillon, the IWC-manufactured 94805 calibre also features a perpetual moon phase display that will need to be corrected by just one day after 577.5 years. The little prince stands on the moon. A 96-hour power reserve is stored in two barrels. The platinum case has a whitish sheen, which underscores the high quality of this complicated Pilot's Watch and provides a beautiful contrast to the blue dial.

Calibre Family 94000

The hand-wound movement features two barrels including the constant-force tourbillon, the astronomical module in the Portugieser Sidérale Scafusia and the digital Pallweber display.

Moon phase display

IWC’s moon phase displays are not just aesthetic works of art – they are extremely precise and diverge from the actual phase of the moon by just 1 day in 577.5 years.

Constant-force tourbillon

With the patented constant-force tourbillon, IWC elegantly combines two complications that serve to increase timekeeping precision.
