M2
Titanium. Mu-metal magnetic shielding. The NATO chronograph entered Bundeswehr service in 1984 — this is its successor.
In 1984, Tutima was asked to build a chronograph for the German Air Force. The rest of the industry had moved to quartz — mechanical movements were considered obsolete. Tutima built one anyway. Pearl-blasted titanium case. Mu-metal inner case — a magnetically soft nickel-iron alloy that blocks external magnetic fields before they reach the movement, the same shielding used in MRI machines. Pushers and crown sit flush with the case — a military requirement to prevent snagging under flight gear. Sapphire crystal 2.5mm thick — roughly double a standard watch crystal — anti-reflective on both sides. Flight tested at 1,500 meters and 15 kilometers altitude. NATO acceptance certificate. It spent a week aboard the MIR space station. The German military still maintains two workshops in northern Germany devoted strictly to repairing these chronographs. The M2 is where the conviction started.
Selected by the Bundeswehr in 1984 — when the rest of the industry had moved to quartz.
In Context







Heritage

NATO Ref. 798 (1984)
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.”
