In another thread I indicated my belief that Hamilton would put whatever dial a purchaser desired on any watch. I have a couple private label watches that have matching dials that "should not" have been present. Hamilton was not dogmatic. I was challenged about this and I did not have time to find the silver dial notice below. While I have read that others call this a "service dial", the note speaks for itself. It clearly states the factory will put this dial on new watches as ordered at "no additional charge" over the typical double sunk enamel dial (isn't that nice of em). I forget who originally brought this note to light (Robert Sweet?, Don Dahlberg?)), but I downloaded it some time ago. The watch is my favorite 996 in a silveroid case. So, IMO, unless there is an obvious reason to believe the dial does not belong (Signature correct for watch S/N) then I do not assume it was switched. Particularly when the story behind the watch does not support a swap. Like the case switching (1st model 992s in 1930's Hamilton RR case) done to please self-appointed experts, indiscriminate dial switching can confuse the historical record. Of course, I believe the current owner can put whatever case, dial and hands on a movement they want. But we should not use dogma as the reason.
