Im trying to identify my late fathers Seamaster bought for his 55th bday in 1985 . I was with him when he chose it in what would have been late 1984 early 1985 for his 55th from Mum in May 85 and was his daily for over 30 years . Its been suggested its a Greg Louganis 1984 Olympic edtn and now I know the serial no it matches 1984 numbered starting 47 but I cant locate any info on such a watch anymore thou did once find a description written on the net somewhere and it matched no pics thou . I cant seem to find it or any other info . The Omega vintage has a very similar one pictured under the calibre no a 1983 Mariner . How do I get the full serial no run to identify it ? Circled is where I used several photos zoomed it to obtain the 8 digit serial no .
