I purchased online the Theorema Casablanca GM101-4 and when it arrived there was 2 defects. One of them is that the strap is brown and not black as I have ordered it and the second defect is that there is a small "blue ring" inside the case. You can see it attached, sort of like, next to the 45 second marker inside by the front glass. Pictures also have been sent via email to Emilia.
