actually the fraud chrono doesn't bother me much cause i barely use it and can't tell whether it's functional or not on wrist, but the date window is tooo thick, which need put larger tolerance on that (and the case back is sightly thicker as well, as above said the gen is about 12.6, but the rep is about 14mm), but one good thing is the lume is superb.... so how to say, as the nautilous chrono v1, it's overall good but still need improvements though ...
