The case is made of German ThyssenKrupp 1.4404 standard steel (same as 316L) to improve the wear resistance of the watch case. True to tradition, with a refined onion classic pilot crown.
Super luminous surface
The traditional blue steel arrow pointer is filled with ice blue super night light to ensure that it can be read clearly in the dark sky. Not only the pointer, but also the most environmentally friendly non radioactive luminous material super luminova is used to make the luminous surface. After being exposed to natural light for 10-20 minutes, the luminous surface can last for 4 hours in the dark.
