Anyone can help me to check this is an authentic watch ?

 

It’s a Speedmaster reduced, automatic movement, smaller and much cheaper then a Moonwatch aka Speedmaster Professional as they tend to cost a lot more to service.

It’s also an omega not a Longines.

 

...And has fake aged lume?

 

They came in Tritium. That just looks mossy and poor condition unless I’m missing something.

 

I can’t see any T Swiss T though to indicate Tritium on the dial?
I do need bifocals though according to my optician.

 

The requirement to have the T for Tritium was no longer in effect by 1990 when the reduced debuted.

 

Thanks Phil for the education as always. Much appreciated- that explains a few things! I have a Tritium dialled Sinn without T’s - so now I know that Sinn weren’t a law unto themselves and that the Watch is likely circa. 1990!
