So, I'm a little confused about the hesalite/sapphire history on the Speedmaster pros. I don't own a Speedy, but I'm back on the forums now because I'm about to be in a position where I can get the ones I want. When I looked at the histories, they were hesalite. But when I see some Chrono24 and ebay pics of some of the older, pre-moon Speedies, they have that whiteish edge, indicating sapphire. Did Omega use both?
This seemed like a good place to ask from an Omega virgin trying to learn how to detect frauds.
