Once when I was in Vegas, I had my Navi with me, and while I knew it should not be submerged in water, I didn't feel like leaving it in my shoes or something when I went in the pool, so I just wore it swimming. Thank goodness nothing bad happened, and the watch was fine afterwards, but I wouldn't advise taking the risk.
After a few years, I grew tired of the Navi because it seemed too delicate for my lifestyle...I wanted a watch with at least 100m water resistance so that I could take it swimming on vacations and also with a bezel that could protect the sapphire glass crystal better. Ended up with the Crosswind Special and have taken it to vacations...even a water park without issue. I'm very happy with my choice, but the Navi is def a beautiful watch.
