Why are there no good Speedmaster reps?

The entire field has come a long way in the past 20 years to the point where clones with entire cloned movements are very easy to get ahold of, for tons of common, and even not-so-common watches. The Speedmaster is one of those watches that's in the pantheon-of-greats, and I'm surprised that no factory has managed to put out a proper Speedy rep (and especially considering the leaps made for the Daytona).
