Delete photos of your Patek 3940 perpetual calendar moonphase with display back and microrotor???
No way!
We ain’t the Omega police 😁
However, in an effort to get this thread back on point, here is the first SpeedieMoon, circa 1980s, Reference 345.0809.
Unlike the newer SpeedieMoons shown above, all dates on dial face outward.
In addition, this reference features the NoNasa caseback not seen since the rare Speedmaster 1971 version, 145.022-71.
