Victorinox I.N.O.X.: Surviving 130 Extreme Destruction Tests
Frozen in ice, driven over by a 64-tonne battle tank, and dropped from 10 metres: the untold engineering story of the virtually indestructible I.N.O.X.
Victorinox INOX rugged steel watch tested under extreme conditions
When "Durable" Is Not Enough
To celebrate the 130th anniversary of the Swiss Army Knife, Victorinox engineers embarked on a mission: build a luxury watch that could survive anything a human being—or nature—could throw at it.
The result was the I.N.O.X. (from acier inoxydable, the French word for stainless steel).
The 130 Homologation Tests
Before a single I.N.O.X. leaves the Ibach manufacture, its prototype underwent 130 gruelling tests. Normal Swiss watch certifications require roughly 30. Here are just three of the trials the I.N.O.X. passed without stopping:
- The 64-Tonne Tank Run: A Swiss Army Leopard tank rolled directly over the watch on concrete.
- Cryogenic Freezing: Encased in a solid block of ice for 168 consecutive hours at -20°C, then subjected to +71°C thermal shock.
- The 10-Metre Drop: Repeated drops onto a solid stone floor from ten metres high.
Crafted for Himalayan Terrain
In a country blessed with the world's most breathtaking yet punishing topography, the I.N.O.X. is the ultimate field timepiece for trekking the Annapurna Circuit or conquering Everest Base Camp.
