Ray Maker is the first person I’ve seen really test the Apple Watch’s water resistence. He swam with it, jumped in off a 10M diving board with it, and simulated 40M depth water pressure with it and the Watch kept on ticking. While all of this is comforting to know, after spending $400 on a watch for the first time in my life, I still take it off before showering. (I do, however, keep it on while washing dishes.)
