I have the same S XXXXXXX (seven digit) serial number jazz. Does someone have proper explanation for that kind of numbering ?

The first two characters indicate the *approximate* year of manufacture: S8 is 1978 (seventies, 8), E4 is 1984 (eighties, 4) etc. I say approximate because it's not quite that simple! More info here: https://support.fender.com/hc/en-us/articles/212774746
