guidelines for using chronographs

[htc8p]

i have read that its not good for the watch to run the chronograph non stop (as direct drive)

if that is so. what is the usual amount of time to run a chronograph.

maximum of 1 hour?

my opinion is if you want to run it non stop go ahead ... of course its additional wear on the mechanism but hey just running a watch is already wear its what it was made for ... if you service it regularly then you shouldn't have any issues running it non stop

I think that the answer to this question depends on the quality of the chronograph you are referring to..

The chronograph function is almost like an additional watch using the same mainspring and escapement. Some watches simply add the additional gearing and it is not jeweled/bushed or finished to the same degree as the main movement parts..

Most high-end chronographs though, including Rolex, build the chrono functions to the same standards as the rest of the watch.. So, I would then say that you would only see the incremental wear on those parts if you run it continuously.. Additionally, you would see a change in operation; either a change in amplitude (accuracy) especially at low wind, and a loss in power reserve since you cannot add more work to the movement without penalty..

However, I would have to ask, Why ??

I use it to time, wether it's an hour or two, or 5, 6, 7, or 12 hours, no fear in using the function to time whatever I need.

I don't think hours of use are any problem, but constant running will affect the accuracy of the watch part of the package.

I find it hard to believe that Rolex would put buttons on a watch if you couldn't use them at your convinience!

:49 minute run time otherwise the watch detaches from your wrist and runs down the street. Not a minute sooner or later!!!!

Is that just in Spain and Russia or would it happen anywhere that you wear it?
