I have not sean one of these in the flesh yet but there is no reason that it may not be waterproof as long as all the seals are there, they are lubed and the crystal is pressed on propperly, I would advise that you find a local mall watch repairer (not and AD) and see if they can do a leak check for you, it will only cost a couple of $ and then you will know if it has any water resistance. I have a leack checker that i test all my watches on and i swim in the pool in mine and have not had a problem.
