Hamilton 950B
ProbableThe premium grade, and the target of the most common Hamilton fraud: a 992B re-engraved to present as a 950B. The two additional jewels are the physical difference and they are countable, which makes this one of the few high-value alterations in the whole catalog that can be settled definitively by looking.
