I have had a look myself and agree that the image was not as good as the origional.
Then I noticed I could enlarge the image by clicking on the plus sign, for some reason the reduced version fitted to the screen is not as good as the enlarged normal version? Where you do not see all of the image at once. I am probably preaching to the converted here so please do not flame me.
Not quite sure which version you looked at? Screen size or enlarged
Sorry I looked at the large. That is clicked on the image. Anything I say is ment only as constructive-even if I am incorrect :) Around the chronograph. Just my opinion but if it was me I would have smoothed or blurred the edges to make them blend in with the background a bit more.
