The Big Aviator’s Watch Since 2002, the Big Aviator’s Watch has been IWC’s flagship. 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 7 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.
