A question for water lovers

Hi everyone,

I was doing some searching through the forum for info on using one's SMP for water activities. Now I know it's a dive watch, but last year I had to have mine overhauled :sad: because there were spots on the underside of the crystal. They were faint, but similar in appearance to water spots you might get on your windshield. There was no rust in the movement or anywhere else, so I have no idea how it could have happened.

These days I may swim or snorkel with my SMP but I'm still a bit skittish. Years ago when I used to dive I had a Seiko auto and never had a problem, even at 100+ feet down. I have read that swimming might be bad due to the pressure created by the hand entering the water with force. How tightly do you guys screw down your crown/helium valve? Again, any thoughts or advice is much appreciated.

You nailed it LarryD - "And snug is good enough.........any more and you run the risk of deforming the "O" rings and sealing gaskets." And this is the one statement of fact that is invariably missing when the question's asked. If you are diving to the depths possible 2-300 meters or more (even a hundred+ feet), I'd tighten it for the dive and relieve the compression some when surfaced.

Rubber loses it's flex / resiliency if crushed all the time, whether compressed between a shaft & tube or by a cap.
