This one might be a Banker variant unknown for now, it has a 17J 10CL with a M6 date stamp and a Yellow 10K RGP bezel and back. The band is a Speidel expansion style, the dial is off White with applied markers and a printed name. *Update 1-15-13 I can't make out the ink stamped number on the inside of the case back, but the stamped number below it is 2597 Here are 3 "Banker" ads, the case looks the same...
In reply to There is a slight radius arc by FifthAvenueRes…
Looks like the same case as in this 1967 Banker "N" here, and has the same stamped number inside case back in both examples (2597). Different dial configuration- don't know if that makes it a different variant, but I'm good with 1966 Banker (no variant) for subject watch....
