Why This Watch

In 1984, the German Air Force needed a pilot chronograph. The rest of the world had moved to quartz. Tutima built a mechanical one anyway — 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. On your wrist, the titanium is lighter than you expect and warm where steel would be cold. The mu-metal shielding means it keeps time accurately next to your laptop, your phone, the MRI machine you walk past in a hospital corridor. The M2 is where the conviction started.
