I understand the belief that using the function only when needed saves wear to the drivetrain but I have always ignored this advice, choosing instead to believe keeping the oils in play keeps them from thickening. I can only give my anecdotal observation; I’ve yet had to service any of my chronos, even the 23 year old Navitimer and the seriously abused Fortis. Any thoughts on this assuredly already discussed subject?

That a vertical clutch system adds no extra wear on the drivetrain…🤔 this is above my pay grade, though maybe someone can opine?

I have no chronographs at all. So i have no problem with inactive complications. But if i ad one to my wc, a Navitimer would be the first i think of. Not every Navitimer, i will go for very rare and not common one.

I still don’t know the final word on it; whether to run it permanently or use only when needed… Regards
