1957 Banker - white gold plate with case and movement both marked "L7". Crystal appears original and is thick and domed in the center end to end. Case, crystal, face and hands literally spotless. Mounted on a nice ostrich leather band. Accurate runner. Style-wise this is one of the favorites in my collection. I am guessing this is either a Banker "A" or "B". Referenced ad is dated 1959.
Movement Serial No.
Case Serial No.
