I'd have sold my home when the market was up and bought every DON bezel and 321 Speedmaster I could find.
the good side is I have the same one with box and papers (less the bracelet) I also remember paying my parts at Omega in 2005 half the current price.
If you, or anyone else, has that Omega Chronographs brochure (Blue, space walk) could you please share some more details. If pictures aren't appropriate or possible then number of pages and other watches featured would be really nice to know. I haven't seen one for sale yet individually, only as part of a full set with the Speedmaster.
