Last weekend I went swimming in the ocean as I have many times before with my circa-1994 DW-6600. I noticed after leaving the water that the display showed only the seconds bar and the bar above it. The LCD time and date display had disappeared. I assume that the case gasket had finally deteriorated to the point it let in water. I have probably replaced the battery maybe 6 times. I've already won and received a nice, like new replacement from eBay. Is there any way to prevent this happening again save from replacing the gasket at every battery change? A jeweler tried to tell me that once you open the case these watches are no longer considered "water resistant". I love my new watch, but am almost afraid to let it get wet. By the way, the new one must be some sort of special edition as it has what's called an orange "foxfire" illumination button in place of the usual gray button. It also says "fox fire" on the bezel above the button.
