Can anyone tell me what the M with the circle around it stands for on this movement. Is it something special or am I making something out of nothing? Thanks Rob

Sorry guys - but it means "MEDALLION" -- because in early versions that was what was in the circlular spot - a tiny round solid gold medallion, with an interlinked HW engraved on it.

I understand it signified a 982 with better finish.

No Problem I did not think it was important enough to mention in the description anyway. Thanks for all the help.

I had been told that the Medallion movements were adjusted to higher standards than the normal movements. Examination of the Hamilton Repair Shop standards do not confirm this. The 980, 982 and the 982M all have the same timing standards (three positions, 60 sec/day). The difference between the 982 and 982M appear to be just cosmetic.

Hi Robert:

Early records that I have say that the 982M (Medallion) movement "utilized superior damaskeening and finishing of all parts." In addition, "they are position adjusted and timed to closer tolerances."

My records show that the 982 was temperature adjusted but "not position" adjusted as the 982M was. This may be the case for early examples - however, later examples of the 982 may have been "position adjusted" as well but not when first introduced.

Regards,

Will
