Bulova 1945 Spencer
Here is what I believe to be a 1945 Spencer in 14K Rose Gold Plate on the original Bretton band.
Watch is pretty clean, but runs real fast at present. Probably just needs to be "de-mag'ed". Multiple jeweler marks on inside of case back.
Interesting that one ad shows 10K and the other shows 10K or 14K. This example is marked on inside of case back as a 14K plated one.
