close friend asked me how i was able to tell a piece (franck muller) was using a 7750 and it was hard for me to explain, besides saying.. look at it.. its 7750 looks like every other 7750..
and then he asked me the difference between column wheel chrono and vertical clutch... to which i do not know the answer but i am very curious..
was wondering if someone could explain to me/others the differences between all the types of chronographs used in watches and the pro's and con's of each..
much appreciated
