    Archimede Pilot 39 with black PVD case - removing rust?

    Hello,

    I have an Archimede Pilot 39 with black PVD case. After quite a number of months, I went to change the strap and noticed there is some rust on the case between the lugs. I'm guessing some water got trapped where the NATO was pressed against the edge of the case, resulting in the rust. Is there any way to remove or clean the rust, particularly given the black PVD case?

    Cheers,
    evanr

    You might try some very fine 0000# steel wool, but I don't think it will do much good. If you compromise the coating in any way by trying to buff it out, it would need to be re coated.

    PVD is tricky stuff to work with, so you options are pretty limited.

    Good luck.

    Sure it is rust ? If so and it is just on the surface try soapy water and a toothbrush.
    Kind regards

    Thank you both, will give the toothbrush and soapy water a try first! Hopefully that does the trick...

    Thanks for checking in. I tried using an old toothbrush with warm soapy water and it doesn't seem to have made too much of a difference. Part of it looks like the PVD coating has been worn away by the NATO, which you can probably see most clearly on the side of the case back next to the crystal and on the inside of one of the lugs. Other than that, the dark marks/rough area are really hard to photograph and make out in the pics. They certainly didn't brush off, which leads me to believe they are rust. Perhaps someone has other thoughts based on the photos? I can try taking better ones tomorrow...

    I don't think a PVD surface coating is capable of rusting. I'm fairly certain that is the coating itself wearing off.

    Interesting thought. Just curious, there appears to be some marks on the uncoated, engraved letters. Do you think it's a combination of rust there and just the coating wearing off elsewhere?

    It could be, but it's pretty hard to rust a stainless steel watch. And I've never seen PVD rust before. I've seen it wear off and then rust on the exposed metal. It's hard to tell from the pics unfortunately.....
