The new "856.FLIEGER.Ⅱ" will be added to Sinn's pilot watch 856 series. Only 50 will be sold in Japan.
A simple yet high-spec pilot's watch equipped with three unique technologies

Sinn, officially known as the "Sinn Spezialuhren GmbH," was founded in 1961 (at the time called "Helmut Sinn Spezialuhren GmbH") by former German military pilot Helmut Sinn. Since then, its watches have been recognized for their durability and legibility, and have been supported as a partner for professionals working in harsh environments, such as pilots, special forces, and rescue workers.
The 856.FLIEGER.II is equipped with three unique Sinn technologies.
As the name "Sinn Specialty Watches" suggests, the company has developed many original technologies. The newly released "856.FLIEGER.II" is equipped with three unique technologies (Sinn technologies).
Ar Dry Technology
First, there is the "Ar Dry Technology," which uses EDR packing that is weather-resistant, ozone-resistant, and water-resistant, suppresses discharge corrosion with a protective gas filled inside the case, and uses a dry capsule containing a special desiccant to protect the movement and lubricating oil from moisture.
Magnetic Field Protection
Next is "Magnetic Field Protection," which encases the movement in soft iron, making it resistant to magnetic fields of 80,000 A/m.
Tegiment
Finally, there is "TEGIMENT," a surface hardening technology that uses nitrogen carburizing on the case to ensure scratch resistance. Its hardness is said to be 1,200 Vickers, or even higher, the same as ceramic.
At first glance, it appears to be a simple pilot's watch, but inside it is equipped with a wealth of technology that supports accurate timekeeping in harsh environments. This is one of the watches that founder Helmut Sinn sought, and it can be said that this model is proof that his DNA still flows today.
