·I don't know what the reference number is but I've owned a 2000 Speedmaster Professional Moon Watch since 2002 (bought second hand) and even though I've been more of a Rolex guy (Datejust, Sub, GMT II) as well as owning an early 60's Connie redial (two-tone), save for the lack of water resistance, my Speedmaster could be an only watch. I love these things. I have about 15 watches to rotate through and the Speedmaster is in the top 3-4. Wearing it now.
