    Pocketwatch dial problem

    I was bragging about this kind of special 1930 solid gold with metal and white marble like dial. Last time I looked, 10 years? it was near perfect. The metal which may be 2 color gold alloy is fine, but the white grainy areas are going brown. Maybe at time of purchase it had been cleaned with something that left a residue now visible? Suggestions for cleaning? The white areas going brown are not textured metal, not an ordinary paint; i guess i need to identify what it is. The first 70 years appearance looked like new. 10 years mostly in a bank vault was not good for it.

    I'm assuming the third picture (on the purple background) is from "before" 10 years in the vault? Its hard to tell how much of a difference there is, becuase the color balance and lighting are clearly different between the two shots. But I can sorta see the same patern of discoloration in the sub-second dial, just far less pronounced in the before shot. Its likely the dial metal oxidizing underneath the white paint(?). That kind of thing can be cleaned up with a touch of light acid (vinegar), but it'll come back.

    Can it be Silver that is oxydizing?

    Its a complicated combination of solid or plated metal. It was so sparkling white when I got it I thought it was a baked enamel or ceramic. But now I think you guys are probably right and is an oddly bright white crystalline fine grained silver. It will be fun to try a little vinegar on my least desired dial material. Much appreciated.

    Finally. It is all silver. The gold like color is tarnish as well as the brown. I would like to dip the whole dial in tarnish removal liquid (no paint on it). OK? Magnified, the white surface is a microcrystalline matte. On top is the thin polished surface perforated silver. In the past q-tip was used leaving some fibers. At least it is a silver dial that can be renewed easily excepting maybe dulling the fine white silver surfaces?

    I do not see how this 1930 metal dial is secured. Would like to remove for cleaning.

    Screws on the side of the movement?

    A little tarnish remover with fine foam tape recorder head cleaner sticks did well. Second hand was down on surface and movement strong enough to run it abrading the white surface a little. Otherwise good enough.
