There are some spotting developing on the case back. Hope it is not dissimilar metal corrosion.
The case seems to be getting darker.
You can see some 'polished' area around the crown. I guess it is from me winding the watch. Note the 'red' spots along the edge of the case and the spot just to the right and left of the crown.
Note the dark spots near the 8 o'clock position. Also see the lighter area near the strap, between the lugs. That is from the rubbing between the strap and the case.
Some blemishes can be seen.
Strips of 'red' at the top and bottom edge of the side of the case. I will try to take better pictures next time.
