You should also check timezone.com. Look around on the site and you'll find the sale forums. I bought my reduced Speedy auto from an individual at a great price.
I'm not sure if you're aware of "gray market" Omegas, but you'll see them for sale much cheaper, as the SN has been polished off. Omega will not service these watches.
Regarding the crystal, yes, my hesalite is all scratched up because I wear it daily. In fact, there is one scratch that probably would have broken the sapphire, so I see hesalite as a plus.
L.O., good luck finding one, and congrats in advance to another Speedy purist!
