In 1989, I bought an Omega Speedmaster Apollo 11, 20th anniversary model with the fancy gold plated movement, and the crystal case back. It was sold to me by an AD as a "limited edition"! Turns out, it's not a limited edition. The same watch was offered at that time which was a limited edition of 2,000. These watches had the edge of the case on the 9:00 side engraved with xxx/2,000. Otherwise (AFAIK), same watch! So I guess mine is a "special" edition, and not a limited edition. I think the term "limited edition" is over-used!
