The Big Pilot's Watch is a famous aviation-inspired timepiece from IWC that can date back to the 1940s. As one of IWC's most important watch models, there have been innumerable versions of the Big Pilot's Watch throughout its catalog. IWC Big Pilot's Watch Perpetual Calendar Simonetta Orsini 'Buenos Aires, which is a limited edition featured with a perpetual calendar complication we are talking about.
With a very large 46 mm stainless steel case and the oversized 11 mm fluted winding crown, the Fake IWC Big Pilot's Watch Perpetual Calendar 'Buenos Aires' ref. IW502619 lives up to its 'Big Pilot' name. This model is totally different from IWC's Miramar, a vintage-inspired watch. It's also a thick timepiece with a height that spans 16 mm tall. This Big Pilot's Watch wears comfortably mainly since the curved lugs that hug the wrist even if it has immense size.  
With only 40 pieces to be limited, the watch includes a 'Buenos Aires' engraving on the rotor indicating that it was merely made to be sold by Simonetta Orsini in Argentina.
The steel case is matched with a black leather strap, which is folded and secured with large steel rivets, adding the watch robust style. To keep the IWC Big Pilot's Watch Perpetual Calendar 'Buenos Aires' ref. IW502619 secure on the wrist, a stainless steel deployment clasp is included for the leather strap.
At the center of the black dial with white markings and pops of blue accents are the large and luminescent sword-style hour and minute hands. The big size makes the replica watch an expansive dial, which provides lots of information for the wearer. Not only does the watch feature day, date, month, year, and moon phase indicators, but also as a perpetual calendar, these functions automatically adjust until 2100, how an impressive feat for a mechanical movement it is! Besides the calendar displays, the IWC Big Pilot's Watch Perpetual Calendar also has a power reserve indicator and a running seconds dial, tucked within the 3 o'clock and 9 o'clock registers separately.
You can see the Caliber 51614 working away under the sapphire exhibition caseback if you flip the timepiece around. This movement makes use of IWC's signature Pellaton automatic winding system, a more efficient design that winds up the mainspring when the rotor swings in either direction instead of just one direction.
It's worth flaunting that it has an impressive 7-day power reserve, the automatic Caliber 51614 is ultra user-friendly since everything is set through the winding crown. Moreover, except for its impressive mechanical mastery, the Caliber 51614 is also beautifully finished with the coveted circular Côtes de Genève decoration. Additionally, the skeletonized rotor offers a better view of the gears and components that make up the movement.
