I think that the lack of susequent versions of this particular watch is more a function of factory or dealer concerns over demand and pricing. Factories have made subsequent wonderful Omega reps including the PO's. They were the new it watch and with a gen price in the $3,000 price range they could demand better prices. How much can you charge for a rep of a watch that is readily available for well under $2,000. Many of the older Omega Seamasters sell closer to $1,000.
