Here we now date by the case as the movement can be replaced.  As mercury said a year between the movement and case is very common.  We have determined that in the 40's the year is determined by the first digit in the serial number on the men's watches.  

There is a lack of ads during the war years which is probably why we don't see them sooner.  The Minute Man was very popular and it a very nice piece to your family story.  It is very possible that your mother bought it a few years after it was made, probably also because of the war stock, but I am just guessing.
