Limited to 250 pieces, the IWC Big Pilots watch will be exclusively available at IWC boutiques in Los Angles and Las Vegas. “Movement is the Swiss automatic IWC in-house caliber 51614 with Pellaton winding system and a power reserve of 7 days. The moon phase display of the Big Pilot’s Watch Perpetual Calendar Limited Edition 2010 deviates from the actual state of the moon by just 12 seconds in each lunar period. In other words, the discrepancy amounts to just one day in 577 years. All the calendar displays such as the date, day, month, year, decade and century, as well as the moon phase display – which is advanced by the weekday star wheel – are based on an ingenious form of synchronization. All the displays are advanced automatically and take every leap day in the Gregorian calendar into account until 2100, without any need for further adjustment.” (via Timezone).
