Got one of these yellow DW-9600's last week from ebay.de. It's my first Japan made G-shock and it was very cheap and it's gorgeous. (By the way, thanks for the article, Sjors!).
However, when I changed the battery I noticed one of the four back screws was damaged. I don't know how to explain this in english properly, but you know, you put the screw in the hole and it goes all the way down, and you can turn it using the screwdriver all you want and it keeps turning and turning and you realize that it's not attaching the back plate to the watch.
Now my question: Are the the other three screws enough to keep the watch waterproof? The band also presses the back plate against the watch, so I guess it helps, right?
Or should I keep it away from water? Anybody has tried swimming with a G-Shock that only has 3 screws left?
Thanks in advance.
