Jay supposedly took extra measures (and definitely extra $) to waterproof this model of the watch. I've been using this and my SFSO from PT as the summer, beach, pool, shower watches. Absolutely no problems so far. Oh, I should mention that I did (and had to) tighten the caseback when I received the watch (never trust anything but your own QC...)
In also own a 7750 PO Chrono (see my signatue) but that watch has seen no water except a bit of my sweat.....
