In 1984, Tutima was asked to build a chronograph for the German Air Force.
Why This Watch
The Bundeswehr commissioned this chronograph in 1984. Pearl-blasted titanium, mu-metal inner case, pushers flush with the case so nothing catches under flight gear. NATO acceptance certificate. It spent a week aboard the MIR space station. The German military still maintains two dedicated workshops just for repairing these watches. Titanium: lighter than steel and warm against the skin. The mu-metal shielding means it keeps time accurately next to laptops, phones, MRI equipment.

Heritage
In 1984, the Bundeswehr selected Tutima's Ref. 798 as its official chronograph — NATO Stock Number 6645-12-194-8642. It flew aboard MIR, was flight-tested to 15 km altitude and 1,500 m. From German special forces to fighter cockpits, the 798 proved itself in the harshest conditions. The M2 Chronograph inherits this uncompromising instrument philosophy.

“If you ever see a Grand Seiko with a highly polished titanium case and bracelet: Tutima is in no way inferior. Maybe it's even better.”
