The folks at FoneFox decided to put the Apple Watch's IPX7 water resistance to the test. When Tim Cook first announce the device, they indicated it would be resistant to splashes and moisture, but based upon the above video, it's actually better than that.
The videographers started out pushing the envelope by taking the 38mm Apple Watch Sport in the shower with them. The watch passed with flying colors, so they took it to the next level and submerged in in a bucket of water for 5 minutes. Even that wasn't enough to satisfy them, so they actually took the watch for a 15 minute swim in the pool, and it still worked fine afterward!
It's just proof positive that Apple does their best to under-promise, but over-deliver!
*Despite these tests, we still wouldn't recommend folks do what these guys did with the watch, but at least you don't have to worry if it's raining outside or you forgot to take it off when getting in the shower.
