A similar watch sold @ Omegamania/Antiquorum for about US$7,000 in 2007!

Very clean, minimal dings (if any), however the caseback is engraved. I have sent this watch all the way to Bienne and back and it now has a 2 year warranty by Omega themselves! All old parts that were replaced will be included if I decide to sell this.
