Medallion

 

Medallion looks like that because it will almost certainly be plated tin. I tested one of these once with a heat gun. Melted away in seconds (tin melting point is under 300 degrees Celsius. 14K gold, which is indeed what the vintage medallions are made from, melts at closer to 900 degrees).
If anyone wants a black dial 57GS, your best option would be to settle for the reissue SBGV011.
