As the title says how would you remove this "stain" or mark on the metal ?

Does this look like chrome/nickel ? Could this be plated or is it solid metal ? This is a Longines pocket watch from the 1910s in case anyone wonders.

I'm guessing someone may have tried some acid or stone testing on it to see if it's silver ?

I have some of that diamond paste that's supposedly used for mirror finishing but not sure how to proceed here.

Are there any markings on the inside of the case back if its European and silver from that era it will have some form of halllmark on it anyone testing for silver content and leaving a mark like that is an idiot imho.

I would guess at the case being one of the lower grade silvers 800 standard but this would be marked as such.

It's not silver. I gave it a go with one of the polishing pastes that I had and it worked perfectly. Now pondering whether to "shine" the entire case...

I'm guessing it's stainless steel ?

Its probably nickel plated. Stainless didnt become popular in watch manufacture until the  early 1930's it was too difficult to work using method in use at the time and far too expensive a material when first introduced in 1913.

I think the resistance to wear will have more to do with the hardness of nickle as opposed to the hardness of gold which is much softer, pocket watches on the whole fair better than wristwatches having spent most there life in a waist coat pocket.

But whatever the materials used if in regular use it will eventually wear but I have many plated pocket watches over 100 years old that are still in very good shape, but I avoid gold plated  or chrome plated wristwatches of any era because they dont hold up well to constant use once the edges of the plating on the case starts to go its all down hill from there.

      Omega cal. 565 - low amplitude

      By RichardHarris123 · Posted

      @JohnR725 has pointed out many times that the Swiss don't care about amplitude, the timekeeping is the most important.  Give yourself a  pat on the back, great beat error and timekeeping, nothing to be disappointed about.

      I'm bothered but I agree he's a busy man and I don't want to bother him.  In the meantime, we really do need to have other ways of contacting each other

      Second hand watch market.

      By RichardHarris123 · Posted

      This is as complicated as epilame, too many unknowns. The life expectancy in the UK is circa 80, so most people from 1944 or earlier are dead.  Assume they had children at circa 20, they died in 2004. Their children started selling 1944 watches in 2004, so pre-1944 watches must be getting more rare.   It doesn't work though because as you stated some were sold as tat, but since watch prices have increased people have decided to sell when they may not of done in the past.

      Questions about my Bravingtons Renown Mantel Clock

      By Michael20 · Posted

      I was wondering whether anyone could assist with some questions I have about my latest acquisition, which is a two train ‘Bravingtons Renown’ mantel clock - Pics attached I have done some reading about Bravingtons and believe they sourced movements from various suppliers, so I wondered whether anyone recognises this one. I have stripped and cleaned the movement and the clock is now running well, but there are a couple of dodgy brass springs that I would like to replace. I haven’t found anything suitable searching the internet so I wondered does anyone know of a supplier that might help. Last question is about the veneer on the case, it is generally in reasonable condition but there are a couple of patches on the top where the veneer has lifted. So far, I have tried to reactivate the existing adhesive by heating from below and above with a hair drier, then clamping for a day or two. It has improved slightly but the bulge is still visible. I’d be grateful for any advice if anyone has dealt with this sort of repair before.
