Daytona Chrono Question

[jw3571]

I may possibly buy a Daytona. One hesitancy is I love watching the 2nd hand sweep the face on my other watches. Obviously you don't get this on the Daytona unless you have the Chrono running all the time. Is there any problem letting the chrono run all the time? Does anyone else do that?

Some folks do. Doesn't make much sense, but whatever floats 'yer boat.

I asked RSC that very question and all they said was, it does no harm but might slightly affect how soon a service might, he emphasised, might, be required.

What is certain is that the watch will run down quicker. If it’s on your wrist all the time then that’s probably irrelevant.

Constant running would no doubt increase wear, but whether that’s to any significant degree I can’t say. It would seem unlikely to have any adverse impact in the short term certainly.

Let it run. Live a little

Some tests have been published here. If I remember rightly, running the chrono all the time made only very marginal difference to the power reserve, less that 5% reduction.

Thanks for the info

I’m not personally familiar with the Daytona, it’s a pretty rare bird in these parts in non blinged-up trim. But my Speedy is much, much worse than that, though I’ve never formally tested it.

[kilyung]

It’s not a big deal. Just run your chrono if you need a second hand. You’ll need a service well before it becomes an issue.

[jw3571]

Thanks guys, i'd only use the chronology if it as on my wrist.

[subtona]

Modern movement running the Chrono no Issue

I believe that is not true for the previous zenith version.

Great watch.

[Mystro]

It is a legitimate observation as the sweeping second hand is relaxing to watch. I got use to my chronograph large second hand not moving after awhile. I do let it run on occasion and haven’t seen any time keeping issues.

[landroverking]

While no real issues. I never have.

I think it would annoy me but as someone else stated "whatever floats your boat"!

I agree with the other readers that in a vertical clutch coupled chronograph, the wear and tear is pretty insignificant, if you want to let the chrono run, so be it, let it run but give the Chrono a rest during weekends.That's what I'll do
I'm pretty sure the Daytona's Cal 4130 superior fully integrated vertical clutch Chrono will not be affected by running the chrono 24/7. The Cal 4130 has what ?...An awesome in-your-face 60% further internal friction reduction right? In other words perhaps near friction free

I can certainly tell you that if you run the Chrono 24/7 on Omega's
1)Speedy Pro 1861 horizontally coupled chronograph, wear and tear will occur since you have one wheel that is constantly turning engaging with another that is stationary.So that's earlier servicing!
In Vertical clutch chronograph ,say Cal 3301, when the chronograph is stopped , there is some friction between the brass part of the main wheel train and the steel parts of the chrono.When the Chrono is started, the whole brass-steel assembly turns between 2 jewels creating a load.

From a performance point of view in both vertical and horizontal clutches when measured with a timing machine, the balance amplitude can drop and amplitude loss affects accurate timekeeping

So personally speaking not that it matters to anyOne here, I wouldn't leave any Chrono of any watchmaker brand running 24/7 365 /12

What's she said....

Actually, very informative post. Thanks for sharing.

Damn. I wish I knew that on my own!

Options:

1. Enjoy the running seconds at 6 instead.
2. Leave the chrono running. It won’t hurt anything.
3. You can’t enjoy the seconds hand if you’re not contemplating the watch. So, when you want to watch it for a while, press start.

I enjoy the interactivity of the chrono, and miss a date way more than I miss a large sweeping seconds hand.

Bonus, the subdial seconds appears even smoother since you can’t identify each beat as easily on the smaller hand.

Just to add on a related query, I noticed the chrono hand doesn’t rest entirely dead centre at 12 o’clock, probably a very very slight off centre to the left. Does anyone else have this ‘issue’ as well?

It’s not uncommon.

I’ve noticed that sometimes it’s the angle you’re looking too or a weird eye dominance thing.

I’ve seen some where closing one eye makes it look exactly centered (such as when looking with a loupe) while looking with two eyes it looks a fraction of a mm off to one side or the other.

I let all my chronos run all the time, I have never had an issue. Synchronizing the sweeping hand on the dial with 6 o'clock sub dial on the Daytona is much easier to read.

I am always impressed with the research you do Ms M.

I run my Daytona chrono hand on all mine when I wear it but that is not very often.

I also noted that on my Omega quartz chronograph and some of my other quartz models the function stops and returns to zero all by its self after a set timing period so there is no real point in setting those to run.

this is what i don't understand. The watch its self is always running and using the chrono function means the chrono parts are also always running. So basically it would be wearing at the same rate as the rest of the watch and that can go a very long time with out service. Right?

I don't see why always running the chrono would make a watch need a service sooner than if you never used it at all, but always had the watch running.

[oldsalt]

When I had my daytona a friend once commented "your watch needs winding"... because he saw the "seconds" hand just sitting there at the 12 o'clock position... I had to explain the chrono function.. he's not a watch person.

cheers

Same here - I’m confused in that one.
When I bought my D500, I did asked my Ad (bucherer in Switzerland) if I could let my chronograph running 24/7 and he told me Yes - it won’t affect power reserve neither wearing parts. All he told me was “all mechanical watches shall be keeping running”
