IW3717 - movement ?

Thanks for the answers to my previous question.Now I'm really getting to like my 3717-04. I'm interested to learn which movement the model uses. I think it may be the IWC modified Valjoux 7750 as the watch behaves very much like other watches I have with this movement. However the minute and hour registers are better than others I have seen so wonder if my idea is correct or whether IWC have put one of their other movements in the 3717.

Thanks in advance and sorry if this is real basic question !

Hi Lawrence, yes the movement is a modified Valjoux 7750. As recommended to me by our Forum friends for my similar question re Fliegeruhr Chronograph 3706, I pass on the following link to better understand the Valjoux 7750 Chronograph movement used in IWC Pilot Chronographs:
