The watch arrived and I swear, I couldn't find those spots s
First congrats, nice watch ;-)
But these "spots" are typical, if you a make a photo with high magnification of an object with a reflecting glas surface. The sports are not on the dial, but small dust on the surface of the crystal. I think everyone, who made this kind of photos knows this problem. You can clean the crystal as long as you want ... somewhere there is a spot. I guess, most of the high res photos without any "spots" are more or less a product of Photoshop.
