Difference between Speedmaster 310 and 311

[ppierce]

Whats the difference in these reference numbers? I can literally buy the 310 right now on Omega's website. Why is 311 more desireable?

310 is the regular Speedmaster Pro with the 3861 movement.

311 is the Ed White with the 321 movement which is the same movement worn to the moon. This watch also has a different bracelet and the straight lug case.

311 is a lot more rare than the 310 and you won't be able to just walk in and buy this one compared to the 310.

super helpful thanks! can't believe there is a watch available to actually purchase direct from retailer website. its a novel concept.

Sorry also forgot to mention that there's a 311 version of the Speedy Pro and that's the prior generation with the 1861/1863 movement and old bracelet along with the 311 Ed White 321 which is the watch I was referring to in my first post.
