Great article, mate. It's great to find another Steemian that's interested in watches. Very informative, too, since I never heard about the Triple Date before.
This is quite the gem that you have, equally complicated and cool. If I were you, I'd definitely won't sell it, since it's far too precious and cool to have, especially as a conversation starter! I do like a Speedmaster (though I'm personally more of a Rolex fan... ), especially the recent Co-Axial Chronometer watches.
I suppose my interest for cars come into play, as you've described it, the Speedmaster line is very much a watch worn by astronauts, racing drivers, and just about many heroes that we've come to know and admire.
