Welcome to the forum calsoertj.In relation to your first question;The Laureus version of the 3910 Portofino has IWC calibre 79320 fitted. This is the same movement as used in the pilots chronographs and is ETA/Valjoux based. Previous versions of the 3910 had IWC calibre 75320 fitted. This is Sellita based.For the best answer to your second query, you should use the forum search function with words like Sellita. The subject has been discussed here many times.Good luck with your purchase and post some photos as we don't see many Laureus on the forum.Leo

Niemann revised by M. Friedberg".I myself do not fully understand the technicalities like our distinguished Forummer Leosweeneypod, but you will see in ii) above, how the calibre numbers changed based on the IWC modifications.
