IWC Big Pilot’s Watch Perpetual Calendar Top Gun Edition Ceratanium
There is always a first and this latest release by IWC Schaffhausen has chosen to put their proprietary patented Ceratanium alloy in full display. This “IWC Big Pilot’s Watch Perpetual Calendar Top Gun Edition Ceratanium” not only used this unique alloy for its case, but also crafted the crown, and bracelet out of Ceratanium. For an overall lighter feel than steel, while providing increased resistance. And remember that if staying up to date is a priority and you can’t risk missing a leap year, look no further.
The 46.5mm case is made of ceratanium, which is a proprietary alloy by IWC that combines titanium with a matte black ceramic treatment. This combination manages to efficiently merge the lightweight and resistant properties of titanium with the scratch resistance and durability of the latest zirconium oxide ceramics.
On the flip-side is an exhibition case back, which allows us to view the inner workings of the mechanical movement. Among multiple moving parts in full display is also a rotor with an 18k gold medallion and the IWC insignia.
It also comes equipped with the iconic big diamond-shaped screw-in crown, crafted out of ceratanium to match the case and provide a cohesive look.
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 matte black dial dial with white Arabic numerals, followed by a ring of minute index markers and slightly thicker markerings 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 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, if it were to keep running continuously. The central matte black propeller-style central hands, red-tipped sub-dial hands and Arabic numerals have all been fitted with a luminescent coating, for an enhanced legibility.
