Looks like you have an original band as well !! These 1930's watches are almost unbeatable for visual presentation.
Is the case on this watch hinged or the regular pop off back?
snap back, no hinge
EDIT: Doesn't the American Clipper "B" ad show an unengraved watch?
This is the 'F' variant, as depicted in the ad.
Yea looks like an F w/ a nice bracelet. Nice watch Admin!
