On my new 5600 I noticed what appears to be a tiny piece of dust under the top crystal. It won't rub away so I believe it is in fact under the crystal. Is there only one crystal on these Gs? Meaning, is there a topmost crystal attached to the rubber bezel with a second one under it for the actual display, or is it just one (in which case there's nothing I can do about it i guess)? And how common is it to see any amount of dust? Can it accumulate over time or did it probably get in there during the manufacturing process? And if dust can indeed build up over time, what does that say about the water resistance?
As for the water spot (or a spot caused by some other liquid), i at first thought it was a scratch when the light hit the crystal a certain way, but quickly realised it was round and definitely a water spot or something like that. but i can't seem to rub it off. any ideas? i don't want to damage the crystal but soap and water doesn't seem to be doing the trick.
