Hiya all. New to the forum as i need some help. Ive just been going through some of my dads old belonging and found an omega speedmaster 125 automatic. Its in good condition but with no box or paperwork. I wanted to know how does the watch face stay in the braclet? I have read that it is removable but should there be an o ring to hold it in place? If so.....where do i get one??
Thanks for any advice
