The Speedmaster comes in a million and one iterations these days. The original is the "Moon Watch". I used to have one. Unfortunately Omega pretty much doubled the price of all their watches a few years ago as did all the Swiss nameplates. I guess they got jealous of Rolex. It's a very nice watch though. I think the Aqua Tierras are nicer though and they have a better movement. if you buy get one with the Daniels Escapement.
