Is this fake??
It looks original but the ref. no. on the case back seems to read 4503. If I'm correct this refers to a SS Ingenieur and not a titanium one (I also thought the titanium Ingenieurs had a different case design and came in full titanium and in a combination with 18K gold). Please correct me if I'm wrong.

ref. 4509
Hi Joao
I can't see your pictures, but the ref. 4509 with cal. 2249 is indeed an Ingenieur model, and quite a rare one. As Michael explained, models with a reference number in the 4000 range are Ladies' watches. This ref. 4509 belongs to the new reference numbering scheme introduced in the early seventies, while the other he showed belongs to the previously used scheme.
The ref. 4509 (as well as its smaller sibling 4508) were called Ingenieur SL "Titanium Spanish Olive". Together, they were the first Ingenieurs made in Titanium and actually belong to earliest examples of titanium watches ever made (after the Porsche Titanium Chronogramph and Seiko diving watch). They were only listed for two years (1983/84). The first document I have which make reference to them are price lists from July 1983 (ref. 4508) and Oct. 1983 (ref. 4508 and 4509). Both models were then priced ad 2950 CHF.
Both models featured special coating for hardening the surface and producing the "Spanish Olive" look. Because experiences were not always positive (difficult to repair when scratched), surface coating of Titanium was later abandoned by IWC. In 1985, a new model range (later to be called "Ingenieur in Titanium and Yellow Gold") was therefore introduced.

No cause (more)
Hi Greg
All the merits belong to Albert Tanner who kindly provided me with these scans. His incredible collection is also the source of the attached information about the ref. 4508.
