Don't forget the Omega Speedmaster automatic has been worn during spaceflight missions.
For example: July 1997 during space shuttle Columbia mission STS-94 by astronaut /mission specialist Michael Gernhardt who wore an Omega Speedmaster automatic triple date.

As above. The Reduced and Triple date share very little in common. Different gravy altogether.

Over the last couple of years I have followed several discussions on different forums debating what exactly is a "Reduced", and why the "39" is not. Most centered around the Valjoux 775X models having a different subdial layout, as well as a date. Having just read that excellent article at the link posted by Fallout Boy, it seems to validate that contention. I just don't know as, for instance on the Reddit forum (entertaining and brief, but not having the authority and depth of OF), I frequently see the Valjoux model owners referring to their watches as "Reduced". I have done it myself, until several people told me that it was incorrect. Is this "threequarterplate" essay pretty much the final word?
