wow...an automatic early edition! seldom seen! As docC says, the gold insert is missing.....I think since your version is all SS, your bracelet could have been on a 2 toned gold/ss version....I saw such a model on the Japan Omega auction 2 toned seamaster quartz with the missing clasp insert.
Just searched the auction again and found this SS quartz version but with clasp gold insert!.
and here is another combo which i thought was the norm....gold bezel with single locking clasp and gold insert....
