Funny you say that...
Last night I was changing the strap over on my Blue Silverstone (thanks Ron!) and again noticed that if I look at the dial "straight on", the crystal is 100% clear, but if I look at it from an angle, the dial looks a little blurry. If I look at the dial from side-on, its blurred ot the point that I can see the white reflection from hands reflected into the crystal. Not sure if I have described that well, but in short, I think that I have the same issue, albeit maybe on a smaller scale
I am pretty sure that there is no moisture in the case, and the crystal was new when I bought the watch.
So what can others tell us? Is this a characteristic of the Silverstone crystals?
