The Omega Speedmaster Professional "Moon-to-Mars" Ref. 3577.50.00 with Lemania 1861 chronograph movement - $4250 with PayPal fees, shipping, tracking, and insurance included.
I bought this about two years ago and have probably worn it about 20 times since. It is just not to my taste, and you can see from my signature and posts that I have a big assortment in my collection that probably defies a logical coherence.
So put me in the camp that does not love the Speedmaster Professional, even one that has the pretty planets and moon on it. Everything is included: boxes with cracked leather (thanks for the quality control, Omega!), cards, papers from 2012 service, etc. Minor desk swirls on the bracelet. No marks to note on the case or Hesalite crystal (look for the Omega mark on photo 6). Colors on the dial are still vibrant and true. Bracelet is tight with minimal flex. Watch works beautifully and is in near mint condition. It is numbered from the limited series, c. 2008.
$4250 is firm by PayPal as a vendor so you and I are protected. Watch will be shipped with insurance and tracking from South Korea; usually takes about 5 business days to anywhere in the world. I have done plenty of successful buys and sells on WUS, feel free to check around.
Only trades of interest would be: Omega Globemaster (white dial on bracelet), Rolex Explorer II 216570 (again, white dial on bracelet), Rolex Milgauss GV, or something by Glashutte Original. A little cash one way or the other is possible for the right piece.
Thanks for looking!
