The only time I would run the chrono would be to time something. Otherwise it seems kind of pointless to allow those hand to just whiz around.When you put it away for the night, do you stop the chrono from running? Is there any harm to letting run all the time. I would guess starting it stopping it puts wear on it as well?
Indeed. I love the feel of the pushers clicking too. But I can't stand the asymmetry of the second hand and subdials when they're not at 12 so I tend to leave it off :-(Only to time something? Aw c'mon, why so serious?
I don't let my chrono run all the time, but I KNOW I can't be the only person who just likes to see the chrono sec hand run around the track *for a while* for no reason.
I love to see mine run every now and then: I press the pusher on mine, when I'm stuck in traffic in a cab, or a boring meeting.
A whole world of wondrous beauty just opens right up before me,... while the dull world of reality of honking and gobbledygook just fades...
SD movements power reserve is higher if you leave chrono running, that is correct. I read it from some Seiko-catalog I have. Someone said that it could be close to 100 hours, but not sure about that.So reportedly there is less wear when you keep a chrono with vertical clutch engaged (running) rather than disengaged. That's interesting. I am not sure about the mechanics of it. But this may be why I have the impression that I get slightly HIGHER power reserve when the chrono on my SpringDrive Chrono 5R86 is running. Strange, no? A friend with a Ph.D. in physics told me that it might have something to do with the gearing running more efficiently under a certain load, same as with a car. Sounds plausible. But maybe my impression just deceives me. I have never actually stopped the time because I don't like to reset the watch and I wouldn't be able to wear it for more than six days since PR is 72 hours.
