I opened an Omega! My friend brought it back from America. I don't know much about watches ... please advise!
This watch is an Omega Butterfly series, but your clasp is a motorized Altman series, and 25 Swiss-made gems are Swiss symbols on a heavy hammer ... But your watch is not the same as the original one ... Unfortunately, your watch is an imitation ... Now it is possible to buy an imitation in a specialty store ... Be sure to read it clearly in official website before going there next time. Beware of being cheated!
