Hi all , In order to upgrade my small Omega collection I'm considering a Speedmaster 3592.50 cal 863 , serial number 48.269.xxx , sapphire display case back with Apollo XI engraved on it . I still waiting some pictures and tomorrow will meet the owner . The watch is full set , gray leather box , outer box with red Speedmaster writing . In case I will part my 1861 Speed from 2002 . What you think about ? Is it worth it to be added ?..and sacrifice my Speed 1861? Last but not less important , which could be price range if really as the seller (private collector) has described it? Thanks for your suggestions and will add pictures as i receive.
