Does anyone know about the "blued" caseback logo on the back of some Omega Speedy moonphase 345.0809's. I see some have them and others not. Here is an example of one with blue logo....Thanks

 

Its an original sticker from factory that did not came off.

 

I guess this small plastic sticker makes them way more valuable ?

 

That’s Rolex. This could open Pandora’s box over here.
