Love it - I've got Mission to Earth (I actually really like the blue/green color scheme) and its my casual daily; I have two Mission to the Moons - one original and one limited ed. Strawberry edition. I'd like to collect the rest of them, especially Uranus (for the comedic factor).
I love the Moonwatch - I was gunning for one myself but fell in love with the Heritage edition Speedmaster - I feel it is more versatile and casual and less recognizable. I'd love to get a meteorite Apollo 11 Speedy, too, as well as a Dark Side Apollo 11 Speedy and 007 edition Seamaster. But now I'm just dreaming out loud of having a $100k watch collection (my wife would kill me).
