Dear community,
I contacted IWC regarding the below question one month ago but did not get a response, so hopefully this forum can help me. I bought a Portofino Chronograph which has the calibre 75320. However, I do not find any information on this calibre in the IWC catalogue (chapter "Technology", page 18 f.). Instead, I found hints on the internet that this calibre is actually not an IWC calibre but an ETA calibre.
As a result my question is if this calibre 75320 (Portofino Chronograph) is a real IWC calibre and why it is not listed in the IWC catalogue together with the other IWC calibres.

Hi Schiefinho
Welcome to the forum and congratulations on an excellent purchase and a beautiful watch - I am currently considering the same. My (limited) understanding is that the Portofino Chronograph ref 3910 actually has the Cal 79320 (not 75320). The 79320 base is ETA 7750.
Confusion reigns here. The Portofino Chrono originally used a modified Valjoux 7750 movement made by ETA to IWC's specifications (calibre 79320). More recently, most Portofino Chronos use a movement made by Selita to IWC's specifications, hence the different calibre number. Both movements are nearly identical in design, quality, durability and accuracy, and are good movements.

Thanks for the clarifications and very quick responses. So if I understand correctly, the IWC 75320 is a good movement which was not manufactured by IWC but by Selita based on IWC's specifications (so an outsourced part). That's no problem - I was just curious because I did not find it in the calibres list in the catalogue. I am really happy with the watch and also the calibre. It actually runs for more than 52 hours and not only the specified 44 hours. Very strange, IWC was never in my focus, but when I saw it at the watch dealer next to various Omega, Longines, Breitling, Rolex watches - I really fell in love with this model and still am. :-)

Schiefinho, welcome to the forum and arriving in grand style as you do with a new Portofino Chrono - simply amazing and cool watch!
