I recently bought Omega Speedmaster MK40 3520.53.00 Omega caliber 1151 Movement, I have a couple of questions that I am hoping someone here can answer for me.
Firstly are these faked and if so should I get this watch checked out by an expert?

And lastly, what is the point and how do you use the small blue and black sub dial? One hand moves like a second hand while the hand with the arrow at the end moves around slowly.

Any advise would be greatly appreciated.

Cheers
Craig
