Watch as this gentleman performs a meaningless test, the watch was not on his wrist when he repeatedly struck it with a sledgehammer, so the test doesn't meet real-world conditions. If he wanted to test it, he'd have worn it and found someone to swing the hammer. Maybe try TaskRabbit?
What a waste of a very expensive watch. The disappointment that after repeated hammer blows, the front and back were intact, but the watch had stopped turning on felt odd to me, as I was impressed with ONE hammer strike. Poor table.
Additionally, if it can not stop a bullet the watch has less utility than a run-of-the-mill Amazonian bracelet and can not be called "Ultra."
