I read a post in here that the 145.012 67SP is more desired than that of an ST. I know what the SP stands for but it appears to me it would be less desirable as a collectible with regard to quantity during the time period. Thoughts?
SP only stands for "special poussoirs", meaning that the pushers have been improved, whereas "ST" means Steel. Even if there are a few (very few) 145.012 not engraved SP in caseback, I think that all 145.012 got the same pushers
It was all to do with improved water resistance, including gaskets etc. we have a detailed post on it somewhere.
I did the same question to Omega; told me that SP stands for special in reference to watertight. Giuseppe.

That's right. I found the thread where we investigated it. The answer is in post #26 http://omegaforums.net/index.php?threads/Speedmaster-Caseback-"sp"-Reference.2482/
