IWC Big Pilot’s Watch Perpetual Calendar Edition Racing Green
High-speed racing is no doubt a complicated endeavor, so a watch packed with complications seems a fitting match. The link between the two is found here on the new “IWC Big Pilot’s Watch Perpetual Calendar Edition Racing Green”, named after the green international motor racing color of the United Kingdom, that originated at the historic 1903 Gordon Bennet Cup.
The 46.5mm case is made of matte black ceramic, which is formed by polycrystalline powders mixed with several auxiliary materials to form a homogenous mass, that is then shaped and sintered at high pressure in a kiln. Meanwhile this specific color is the result of combining zirconium oxide with other metallic oxides. 
On the flip-side is an exhibition caseback made of Ceratanium®, which allows a view to the inner workings of the mechanical movement. It showcases several blued screws, purple jewels, and a rotor with an 18k gold medallion decorated by the IWC insignia.
It also comes equipped with the iconic big conical shaped screw-in crown, also made out of Ceratanium®, which is based on a specially formulated titanium alloy developed by IWC. 
All topped by a sapphire convex glass with an antireflective coating on both sides. The glass is secured against displacement by drop in air pressure. Water-resistance on this watch can reach up to 60 meters (196 feet). 
Time is exhibited on a Racing green dial with white Arabic numerals, followed by a ring of minute index markers and slightly thicker markings for every 5-minute increment, except for the 12 o’clock position that features IWC’s iconic triangle with two dots.
The perpetual calendar is expressed via three sub-dials: a date dial with a power reserve in its midst at the 3 o’clock position; followed by a month dial at the 6 o’clock position; and finally a weekday dial with a sub-seconds in its midst at the 9 o’clock position. A touch of red has been added to the color scheme at the arrow-tip of each sub-dials hand, plus the final portion of the power reserve.
A slightly bigger sub-dial features a Moonphase with displays for both the north and south hemispheres at the 12 o’clock position, with a small “N” and “S” indication for each orientation nestled inside the silhouette of jets. 
There is also a year aperture positioned between the 7 and 8 o’clock positions. The perpetual calendar is quite accurate and won’t require a correction until the year 2100, while the four-digit year display can continue to function until 2499. The central gold-plated propeller-style central hands, sub-dial hands and Arabic numerals have all been fitted with a luminescent coating, for an enhanced legibility.
