I know where the name 'connie' comes from...

I think of Alec Baldwin playing Juan Trippe every-time I say or read the name Connie.
The aviator is a sensational movie. And apparently the namesake plane was a sensational aircraft- when it didn’t suck a window out during pressurization. My step-father flew as a passenger on many and always remarked on how amazing of a plane it was.

I recall seeing the SAC (Save-A-Connie) Constellation on the air show circuit many years ago. It was a big deal the first time it came to our local show - I was involved in running security for that show for about 15 years. We had a lot of interesting aircraft come to that show over the years I was involved, MIG 29's from Ukraine not long after the Soviet Union broke up, the "new" at the time B1, B2, F117A's. The U2, Vulcan Bombers back in the day, C5's, An 124, and just about every fighter you could think of. The SAC created as much buzz as any of those did.

Quite a beautiful aircraft...

On the old Omega Museum's website, the Constellation page said:

"In astronomy, the term constellation refers to a group of stars whose movement through the celestial vault is consistent and predictable. What better name could there be for a line of watches whose name became synonymous with the world's chronometers?

In watchmaking, the name Constellation has been closely linked with the art of creating luxurious precision watches at the highest level since 1952, when Omega launched the family. It has always been defined by the combination of sumptuous yet elegantly refined cases and dials with ultra-precise movements.

The symbol of this line was to be the Cupola of the Geneva Observatory, where Omega had just reset its own record for precision in 1951, surrounded by eight stars representing its greatest chronometric achievements at the world’s observatories including the 1931 “clean sweep” at the Observatory of Geneva where Omega broke the record for precision in every category."

So it's more or less confirmed that the Constellation name originated from the horological significance rather than the plane.
