Introducing the IWC Big Pilot's Watch Perpetual Calendar IW503605 with a stunning blue dial and matching blue leather strap. This remarkable timepiece combines the iconic design of the Big Pilot's Watch with the functionality of a perpetual calendar, making it a true horological masterpiece.


The blue dial of the IW503605 features a clean and legible design, with large white Arabic numerals and a central seconds hand. The perpetual calendar complication is displayed through three sub-dials, showcasing the day, date, month, and moon phase. This intricate mechanism ensures that the watch displays the correct date and month, including leap years, without the need for adjustment until the year 2100.


Powering this extraordinary watch is the IWC Caliber 52615, a self-winding movement known for its precision and reliability. It offers a generous power reserve of up to 7 days, allowing for uninterrupted timekeeping even if the watch is not worn for a few days.


Crafted with attention to detail, the stainless steel case measures 46.2mm in diameter, making a bold statement on the wrist. The sapphire crystal with anti-reflective coating protects the dial and ensures excellent visibility in various lighting conditions. The blue leather strap adds a touch of elegance and complements the overall aesthetic of the timepiece.
