Aim high with our AIR series. With their features such as high resistance or enormous luminosity, which is guaranteed for up to 25 years thanks to the energy-independent Luminox Light Technology (LLT) lighting system, they are the ideal companions for the next adventure. The series has its origins in a partnership with the renowned fighter aircraft manufacturer "Lockheed Martin" that continues to this day. Matching the F-117 Nighthawk, the model 6441 is given an understated look by a combination of the CARBONOX + material and the bi-directional rotating bezel. In addition, the watch combines luminous numerals by Super-LumiNova with Luminox Light Technology (LLT), which guarantees ultimate night vision for up to 25 years through the use of tritium tubes.
