IWC Big Pilot’s Watch Perpetual Calendar ProSet Le Petit Prince
IWC has introduced its new ProSet system for perpetual calendars, allowing adjustments both forwards and backwards via the crown, debuting in the Big Pilot’s Watch Perpetual Calendar ProSet Le Petit Prince. This evolution of Kurt Klaus's original 1985 perpetual calendar aims to simplify setting and correction, eliminating the need for recessed pushers or factory intervention for accidental over-advancement.
- Price: USD 43,100
- Water resistant to 100 m
- 60 hours power reserve
- Not a limited edition
The ProSet system allows all perpetual calendar adjustments to be made through the crown, both forwards and backwards.
The watch features a blue dial, synonymous with the Le Petit Prince editions, paired with a white ceramic case, crown, case back, and buckle in steel.
The case size is 43mm, which is described as a more wearable size compared to previous larger Big Pilot models.
The calendar display has been redesigned to appear colder and more technical, with the seconds moving to the center and the small seconds subdial being removed for a cleaner look.
The movement, Cal. 82665, has a 60-hour power reserve and operates at 28,800 vibrations per hour (4 Hz).
The price of USD 43,100 is noted as not having seen a huge increase compared to earlier ceramic perpetual calendar models from IWC.
