Hello, Could anyone tell me if this is a real Omega and if so how this one is called, is gold plated or solid etc? I couldn't find any similar watch on the internet. On the backside the number " 53028047 " is engraved. Also the number "20" with next to it the Omega logo is engraved on the side. On the inside of the wristband "fixoflex®" is engraved. Thanks, Nathaly
