Omega Dynamic III 5200.50 bracelet question

I can only confirm that the original bracelet for these is the 1570 with 870 end links.

Also this bracelet is does not really like hairy wrists.

To be fair to the OP, I think people have misunderstood his question. He is not asking for the number or spec of the actual DIII bracelet, he is asking does the Speedy Reduced bracelet fit the DIII case. At least that is what I think he is asking! Both bracelets are for 19mm lugs but my best guess would be no it won't fit since the Reduced has a different curvature and case diameter to the 36mm DIII. It does looks similar though so maybe changing just the end links might work.
