I was hoping whether I could get some advice from you all regarding a Omega Seamaster Cosmic I am envisaged to buy. http://www.chrono24.com/en/omega/seamas ... 284031.htm
I noted this gold plated watch at a juweler in Amsterdam, which seems to me like a seller I can trust. It also seems to be in good shape and the seller ensured me that everything of the watch was original (allthough there is no official paper work to confirm such).
However, I noted the same watch elsewhere from a non-professional seller, which is only different in the fact that the day date is in English, instead of in French as is in the watch from the jeweler in Amsterdam. http://www.chrono24.com/en/omega/seamas ... 861129.htm
However, I noted another difference which feels strange to me. The second watch has on his back side an inscription of the seamaster logo, together with a code that seems to be some sort of serial code. These inscriptions do not appear on the back side of the first watch from the jeweler.
I find it strange that two watches who seem to be the same and from the same era, have two difference back sides. Might it be possible that either one of them has some non-original parts in or on it?
I hope someone might comment thereon.
