Mint condition IWC Flieger Big Pilot watch IWC model reference number IW5004, originally purchased from Kenjo in New York in 2011, it was returned to IWC via Blowers in 2012 for a full service and comes with papers from IWC to support this. This is the second version Big Pilot with red accents in the power reserve. In 2002, the Big Pilot’s Watch became IWC’s flagship product. Its IWC manufactured 51111 calibre – one of the largest automatic movements in the world – contains all the features that have proved their worth in the long history of IWC mechanical watches. Within no time at all, the automatic movement generates a power reserve of 8.5 days, but only runs for seven before an ingenious little mechanism automatically stops it. This is because the torque that drives the movement decreases as the mainspring winds down, leading to a loss of amplitude in the balance and the unacceptable possibility of inaccuracy. Being know as the Big Pilot, as the name suggests, this is a large watch and designed to the original war time pilot size watches. They needed to be big for pilots to be able to see them instantly with high visibility when reading off cockpit instruments.
