The 46-millimetre Big Pilot’s Watch Edition “Le Petit Prince” features the IWC-manufactured 51111-calibre movement, which has a 7-day power reserve. Within no time at all, the spring-mounted rotor and Pellaton pawl-winding system build up a power reserve of over 7 days, before the movement is mechanically brought to a halt by a complex train in the power reserve after exactly 168 hours. The power reserve display at “3 o’clock” provides a reliable indication of the time remaining until the movement comes to a stop. The Big Pilot’s Watch has a date display at “6 o’clock” and the central seconds essential in any watch used for flying. With its soft-iron inner case, it is optimally shielded against the influence of magnetic fields.
This Pilot’s Watch has an engraving on the rear of the little prince with his cape and sword.
