    Re: --- A Guide: Buying / Modifying / Repairing VOSTOK AMPHIBIA ---

    a lot of the older Komanderskie's I buy have that brassy patina that I am guessing is the brass under the Chrome coating bleeding through. Does anyone know how to remove it to make the Chrome bright again and get rid of the brass tint? I tried buffing and that doesn't seem to work. Thanks guys, James.

    I suspect that it's more than likely the appearance of tired and worn TitaniumNitride (TiN) coating. I'm unsure of the method required to take it back to Brass.

    Are you saying that the cases are chrome plated and there are areas where the brass underneath is visible or is it as Mario says?

    Precision in description is important !!


    TitaniumNitride (TiN) coatings are used on some Komandirskie cases.

    Instead of a chrome coating, a TiN coating is deposited onto the brass case. This gives the appearance of bright, polished brass which resists corrosion and helps prevent the green / brown colour of exposed brass.

    I think it is patina, the cadet has a slight brass color but the 53 case is bright silver, isn't the coating underneath the Chrome on the cadet bleeding through?

    .
    Mario is correct.

    The Cadet case with black dial is Titanium Nitride (TiN) coated brass.

    The other case is chrome plated brass.

    TiN has a brass / gold colour so it only appears to be brass bleeding through.

    That Cadet is in nearly new condition so the TiN coating is completely intact.

    The brass underneath is not visible. No need to worry. All is good.

    As with chrome plating, the TiN will degrade with wear and become scratched on the areas which receive the most abuse such as around the crown and where the bottom rubs on your arm.

    Clean TiN as you would chrome. Just soap and water and soft cloths and soft brushes.

    The hands may have patina but those appear in good condition.

    Brass hands are less protected from moisture in the air and often develop patina and sometimes corrosion.

    For brass / gold cases, I like dark dials.

    Green, blue or black.
