Sorry to say guys, but mine arrived a minute ago and no medallion. Just cheap stainless steel screw-in case back. Bummer. They cheaped out on this one. YMMV.
Still a nice looking watch and the only Titanium SAS I know of.
I wouldn't hold my breath finding one for a reasonable price, especially with the medallion case back and the recent rocket launch. Those Sunday Run daze are long gone.
i really really miss mine. I had two SASs in my collection and sold off my blue NASA Apollo because A) my other SAS was a gift from my wife and B) I knew I could get a nice return on my SAS Apollo. But man, I will I didn't sell her.
I couldn't see anything on this link besides an Invicta collectors facebook page. But the NASA Apollo was a ltd edition with the apollo medallion used as the caseback. they later re-released the watch as a regular SAS model without the collectible caseback.
