The case is 10K yellow gold filled and two dial options were available. Both dials are sterling silver with 18K gold numerals but you had your choice of a butler finish or a finish in black and gold.
Under the dial is a 19 jewel, 12/0 sized 753 movement.
Black dialed watches are typically less common than silver-colored (butler finished) dials and thus typically command a premium. I was lucky to find a black Medford very early in my collecting days and I've tried to land a silver Medford a number of times but I haven't landed one yet. I think it's a desirable model and usually draws a premium.
Here's a white-dialed version of the Medford that a friend of mine recently gave me.
