IWC PD Ocean 2000: How many Pieces produced?

Hello!

Does anyone know, how many pieces were made of the Ocean 2000 ?

Ref 3500 ...?
Ref 3504 ...?
Ref 3524 ...?

Best regards

ps. didnt find any Infos about the pieces made

The well known ledger from IWC stops in 1974.
Before that year it was possible to see how many calibers were made, but that is of course not the same as models because a certain IWC caliber can be built in several watch models. Although collectors have asked IWC during collector meetings in Schaffhausen and in Geneva to reveal numbers produced after 1974, the manufacture has been very scarce with information. Many of us wanted to know how many pieces have been made from certain limited editions. For sure some limited editions have not been produced in the full (limited) series, if the watches were not sold as IWC expected. One of the reasons is the fear that such information can be used by forgerers. Sometimes a limited series was built during several years, because the watch was very expensive (Ref. 5240, Portugieser Minute Repetition). In general little information is released by IWC. In rare cases collectors themselves found out how many watches from a certain model have been made. An example of this is the research by several collectors to find the number of Vintage Portugiesers ( Ref.325).
