Hello I have bought a omega seamaster chronostop1969. It needs a new strap. I think it needs a 1171 with 625 ends. I don t know if it is the correct bracelet for my watch. I looked on line and found a similar watch with a bracelet on it and it was 1171.625 but this was not on the exact model that I have bought.The lug width 22mm. Another one watch has a bracelet that has a 1162.172 ref. Does anyone know which one is correct or could I use either? Can I buy a braclet with different ends and change them? I don t know if it is the correct bracelet for my watch I have spotted one on ebay and I am thinking of getting it. I have no idea if it is a good idea to get it as it does not say anything about its condition. I know the ends on it are 676 ends. Any help is appreciated
