Bombproof Wristwatch Can Withstand C4 Explosive Blast

If you’re looking to buy the world’s toughest watch, you might want to take a look at the Kaventsmann Triggerfish Bronze A2. This little timepiece has been pressure tested to 300 bar (that’s 3000 meters of water pressure), blown up with 10 pounds of C4, and survived to tick another day.

Kaventsmann Uhren is a one-man business run by Michael Barahona Fernandez, who creates all of the watch case parts by hand, in his Berlin workshop. It’s a time consuming process, so only a few of these solid watches go on sale each month. For his Triggerfish Bronze A2 model, the watchmaker used shock-resistant CuSn8 phosphor-bronze, the same material bridge load bearing plates are made of, stainless steel for the detachable back cap, and a 10 mm domed polycarbonate crystal. The finished watch measures 45 mm wide and 20 mm tall, and is a bit heavier than conventional wristwatches, but that’s to be expected, considering its extreme durability. After confirming the timepiece can resist water pressure of up to 300 bar, Fernandez enlisted the help of U.S. Special Forces for the ultimate test – his KAVENTSMANN Triggerfish Bronze A2 against the blast generated by 10 pounds of C4 plastic explosive.
