I believe this site more than any other. On anything.

Welcome to the club Roger,

Most sources you see online use the “Guide” to post the Hamilton serial numbers. If you read the entire post Hamilton Movement Number Listings Preserved by John F. Gelson it will explain the rational of how the authors of the “Guide” determined the serial numbers and it will be easy to understand why those numbers are inaccurate. Just yesterday a fellow member was trying to determine if his Hamilton 992 watch is a correct combination. He stated the movement was from 1934. The case was determined to be from 1928 according to the Wadsworth-Hamilton Case Numbers History and Database. At first it appeared his watch was incorrect but after looking at the Gelson list his movement is actually from 1928-1929 which corresponds to the year of the case 1928. His initial year of 1934 came from the “Guide” which isn’t accurate. The Gelson list is easy to use and accurate.

Thanks again Eugene and Richard...I will go with the Gelson dating of 1939/40 7th run.

My dial as noted is wrong, but aside from mine having a script "Hamilton", it sort of looks like #576, one of the correct dials.

Dang this is fun!!!
