The large black dial of the new IWC watch catches the glance by its bright orange hands and indices. The heart of the timepiece is one of the largest automatic movements ever created. The movement gives an advantage of a seven-day power reserve. It offers a mechanical perpetual calendar complication with a four-digit year display and a moon phase complication featuring the moon in both hemispheres.
The most remarkable thing about the Big Pilotís Watch Perpetual Calendar Limited Edition 2010 is that, in spite of its technical sophistication, it is really easy to operate.
The luminescent hands and indices created in bright orange stand out against the dark background of the dial. The new IWC watch is one of very few models that show the moon as seen in both hemispheres. The moon phase display of the watch deviates from the real state of the moon by just 12 seconds in each lunar period, implying that the discrepancy makes up just one day in 577 years.
All the calendar displays, including the date, day, month, year, decade and century, and the moon phase display, advanced with help of the weekday star wheel, are based on a unique form of synchronization.
The displays are advanced automatically, taking into account every leap day in the Gregorian calendar until 2100, with no need for further adjustment. As a result, it is remarkably easy to use. In case the timepiece has not been worn for a long period of time, the watch owner canít inadvertently set or confuse the displays as it is only possible to advance them synchronously, as one, with help of the crown.
The transparent sapphire crystal back reveals the beauty of the IWC in-house 51614 calibre. Operating at a frequency of 21,600 vibrations per hour, the 62-jewel offers a 7-day power-reserve. When the watch is regularly worn, the spring of the long-running movement is fully wound by the efficient Pellaton winding system in just under two days.
The case of the IWC Big Pilotís Watch Perpetual Calendar Limited Edition 2010 is sculptured in stainless steel and measures 46.2 mm in diameter. The case is coupled with a black alligator leather strap fitted with a folding clasp. It features the rivets and contrasting orange stitches.
