Victorinox I.N.O.X. watches

The Victorinox I.N.O.X. is the Swiss Army knife maker's toughness-first watch, a 43 mm steel quartz sports watch that went on sale in 2014, the company's 130th anniversary year. The name borrows the French word for stainless steel, and Victorinox spells it out as Impact Neutralizing Object for the Xtremes. To mark the anniversary, the brand devised 130 endurance tests for it.

Some of those tests are kept secret, but the published ones include a 1 m drop test, thermal shocks, salt fog, UV exposure, pressure tests and 500,000 vibration cycles for the bracelet. At a 2014 event in New York, Victorinox also boiled, froze and tumbled watches in a washing machine, and the watch has been run over by a tank. The case is 316L steel with a screw-down crown between crown guards, water resistant to 200 metres, with a flat sapphire crystal set slightly below the bezel. Inside is a shock-protected Swiss Ronda quartz movement.

The versions share the 43 mm steel case and differ in dial and strap: rubber straps on the black 241682.1, blue 241688.1 and green 241683.1. In 2015 Victorinox added a steel bracelet (241723.1 black, 241724.1 blue, 241725.1 green), delayed because its deployant clasp at first failed a test of being run over by a heavy vehicle. The I.N.O.X. Red (241719) arrived the same year, late because its red dial had failed the stress tests and faded under UV light.

The paracord models are the Naimakka edition, the black 241726.1 and green 241727.1, introduced in 2015. They come on a strap woven from paracord by Naimakka, with its own buckle, a clear, removable case guard printed with compass markings, and a Swiss Army folding knife.
