I have a vintage Omega Seamaster that has a black face and beads of rice band. Both the case and band are gold colored. Removed the back and the calibre # is 471, serial # 14978***, which I looked up and got the year of manufacture 1955. My question is has anyone seen this color of face and case/band combination. I have looked on several websites and can only find case/band in silver with a white face.
