I wasn't sure how exactly to do it. I have little professional metalworking tools. I'm a lover not a fighter. But I did have some sandpaper S/C 120 whatver that means. I decided to sand away the offending logos. But first I needed to protect the crystal, which was accomplished by placing a large sheet of that sticky roller paper for removing lint from your clothes over the crystal, pressing down firmly and then cutting it exactly where crystal meets bezel, with Xacto type knife. Ready to go.
I found that the sandpaper would be very slow going. Though the letters were not engraved very deep, the sandpaper didn't remove metal as fast as I'd like. Also, the sticky masking disk was getting very tired and threatening to come up in some places. I tried emery boards for better purchase, but still about the same level of obliteration, very slow. I decided to go to the hardware store and get one of those triangular metal files, I think it was XX or X grade of cutting. This worked fine, and I was able to remove all of the logos (I left little bits and pieces here and there, kind of like it that way rathter than totally gone, somehow.) Well, below are the results. I do believe I like it, especially the results of the buckle, but I think the case turned out pretty good as well. I had no idea how it would look, but I'm pleased. Makes it more wearable for me. I dunno.. maybe I ruined it in some ways, but I don't regret my decision.
