This is an authentic Omega cream watch hang tag that came with an Omega Seamaster Planet Ocean 42mm mans 2209.50.00 watch. Your tag measures 3cm by 2cm and still has the original string. The writing on the back reads 22095000, 80988030, 2500.
22095000 is the model number, 80988030 is the serial number and 2500 is the movement number.
These tags are not available for sale individually from Omega and are only ever sold with a watch. This is a rare chance to complete your set so your watch has everything it was originally sold with.
I have given you photos of your watch tag from every angle. Please use them to add to this description.
