Leave the Chrono running on a FOIS
Hi
Probably been asked before but are their any downsides wear, spring run down etc to leaving the large chrono sweep hand running all the time? Thanks for any info Toby ![]() |

my local watchmaker told me there would be additional wear, and also that he would regulate the watch differently if he knew the chrono would be used in that manner. other than that, he didn't say that it was particularly risky to do so.

I don't think this is a good idea.

If you really want to test the ‘spring run down’ it’s easy: wind the watch fully, then leave it for 2 days and mark the time it stops. Do the same for with the chrono running. Compare. Wear : I’m no watchmaker but your watch is running all the time, so I wouldn’t worry about additional wear (it’s a different part of the movement), especially if it’s kept well serviced. But why would one want to let the chrono run all the time? Just my $0.02... |

Some people like a center sweep seconds hand instead of a subdial.

I would love to buy a mechanical chronograph, but staring at that beautiful second hand standing still all the time would drive me nuts. So far that has prevented me from getting one. Who knows though, maybe someday I'll get over it.

I think it's more a question of wear, the 1861 movement uses a lateral/horiz clutch, which should produce more friction when engaged vs say the 9300's vertical clutch.
I always thought: - vertical clutch = okay to run chrono 24/7 - lateral clutch = run when needed |

Indeed. And apparently I need 10 posts to post a link...just found a very interesting read where a watchmaker (Archer) explains it nicely...and that is the same reason why 1861 chrono hands jump when you start them too...had always wondered...good stuff :) If anyone is interested in the link shoot me a pm (or if I ever get to 10 posts I will edit this)...
