What could this be? It is marked swiss made and professional. The movement is 198340xx. Case is 2998-62. Could it be original to this movement and case? It is glossy blueish grey.

 

Not with Professional written on the dial no

 

Agree. Definitely not original to the movement & case (which align with the 2998-62). I want to say that's a 105.012 B1 no T dial. Folks? Nice pics, I can really see those concentric circles.

 

Do a search for blue dial soeedmaster using the search function.

There's a couple of threads.

 

It is generally thought...well by me....that these are very rare Omega service dials.

I have two without professional.

I am looking for one with professional,

So here is my first ever....

@Spacefruit, got a proper prepro dial suitable for a 2998-62 you could trade with OP? Maybe you guys can both come out ahead.

 

Funnily enough....

 

If I could see a picture of the dial that Spacefruit has I might be open to a trade.
