Today's video is part 2 of Watch and Learn #5, which was an overview of water resistance. In this video we explain the various water resistant marks, and the specifications used to rate water resistant watches. We'll end with debunking a myth about dynamic water pressure and its effect on watch seals. Warning! Math and Science approaching!

EDIT: The 2nd equation should result in 4500 Pa, not 450 Pa. That is about 18 inches of water; still inconsequential but an error nonetheless.
