Vintage Omega(?) ladies watch
I find this watch on a flee market, I suppose it's a vintage fake... But prefer to be sure! I try to open it but I can't... On the back, there is a triangle with Omega logo inside and under it, 18K 0 750 in a kind of rectangle. on the left, a hammer head with the number 12 and on the right, a left profil of a human head (I know what means those symbols), under all this "Swiss made". Same on the clasp. The dial seems to be in mother of pearl with "Omega" and "antimagnetic" written on it. The glass is a little bit convex. On the winder, there is also an Omega logo. Sorry for bad picture..
