The worst of several cases I have suffered. There were tiny marks when I bought the watch in 2005 — the seller who was obsessive disclosed the marks and sold it for a song.
I could barely see them, even with the case open. But that was only at the beginning … it got far worse. As they say, Rust Never Sleeps.

“Easily resolved” with $1200 overhaul and new parts in 2015, including dial which is slightly different than the original.
