Hello everybody, I owned an Omega 3520.50 since 1990 bought new from a jewelry. Past year it was robbed and now I bought another one used (since it was discontinued). Now I see some little differences on the watch I just received and although it's seems to be new, I am not sure it's not a fake. In particular: - glass reflects lights in a blue tone (the first one didn't do that), - numbers on the bezel seem to be thinier and slightly darker - the movement makes a strange noice (like a little bell) on the continuous sound on the background typical of automatic movements (the movements seems to be ok and original) - clasp reports all the info about reference etc. as my previous watch but in a different size and proportions That's all what I noted till now, has anybody quite experience on this model to let me know if I have to send it back or keep it? Thank you!
