Congrats! Sapphire sandwich is the Speedy to have IMHO. Beautiful movement to see, great feel when winding, clarity of the dial through the sapphire crystal vs. the Hesalite, etc.) - though some Omega enthusiasts would vehemently disagree (buy what you like, like what you buy).
That said, stay on the list for the Sub. Aside from both having black dials, they are completely different watches and both deserve to be in your collection and worn well (and in good health)!
