To celebrate Victorinox’s 130th anniversary, Victorinox Swiss Army has created an ultra-rugged timepiece that symbolizes the robustness and reliability of the Swiss Army knife. To ensure that the Inox performs under the most strenuous conditions, it has been run through a battery of 130 rigorous strength tests.

The Inox can withstand a 10-meter drop onto concrete, a 64-ton tank driving over the top of it, a two-hour cycle in a washing machine. It can resist -60 to 160 degrees Fahrenheit. And 12Gs of acceleration and deceleration. Moreover, it has been subjected to attack by gasoline, solvents, oils, cleaning products, and insecticides.

To achieve this extremely high level of durability, Victorinox made a number of critical design decisions to ensure such high resistance to virtually anything you can throw out it. For example, the dial is a single sealed piece. The indexes look like they are applied, but they are actually stamped. According to Victorinox, this was a requirement because testing demonstrates that the dial is one of the first things to fail when subjecting a watch to these extreme conditions.

The horns are protected against warping and solidified by a crossbar. The crown, too, is protected, as is the crystal by the slightly elevated (armored) bezel. And as if that is not enough, there is also a removable bumper made of silicone and nylon that can be snapped on to further increase the durability and to reduce the probability of scratching the watch.

The Inox is presented in a 43 mm stainless steel case with a flat sapphire crystal that has a triple anti-reflective treatment. The stainless steel caseback is screwed on, and the crown is screwed down, as well as protected by substantial crown guards. Water resistance is 200 meters. The movement is a Swiss-made quartz Ronda 715. The hour and minute hands are luminescent. The date is displayed at 4:30. Military time is on the flange.

The retail price is $525. Available September 2014. (Ref. 241682 – black, 241683 – khaki green, 241688 – blue)
