Daytona Chrono Question.

[tazzy1]

Is it beneficial to have the chronos working while wearing the Daytona?
I ask because although I wear mine daily I wounder if the oils would dry up on the chrono mechanisms if not being used. I know this would take some time/years to happen but just wondering.
Please let me know your thoughts.

In some circles, as opposed to squares it's accepted practice to run the chrono once a month for at least half an hour. This is to ensure distribution of said oils and to keep the whole movement in tip top shape.

Hell, with a Daytona, especially the 116520, it's lots of fun using the chrono for the heck of it... the tactility of the pusher action... that firm click as it engages... mmmm... heaven...

I don't think it would hurt running the chrono while wearing. The only thing this do is run the power reserve down quicker. It does look cooler with the timer second hand running.

Hey Ron! Good to see ya...

The power reserve on the 116520 is 72 hours... with the chrono running I think it's only down to 40... normally, a chrono can be expected to halve the power reserve of a movement.

Thanks guys it does look good while running! I'll run it a few times a month just to use the oils I think that will be fine, just wanted some opinions.

I asked my dealer ones about the chrono running all the time. It does not really wear anything senefic.

About the powerreserve. I had my Tudor Chrono running all the time. I noticed that the powerreserve went like from 43 hours with no chrono running, and to 41 hours when running. It is only in the very end of the powerreserve, that the spring does not have much power to turn everything around. The Chronowheels only runs along with the normal whells, so that is why there is not much difference in the powerreserve. If the normal wheels stops running, the chrono will always stop running too, and if the chrono stops running, and was not set to do so, the normal wheels will stop too, and the whole watch stops.

Well as to have it running in real terms no benefit,chronographs are meant to be used as timing devises.But cannot see that any harm would come from running 24/7 except for around 5%-10% less power reserve.But myself cannot see any reason to have the chrono function working continually, you have a sub dial for seconds if needed.

Let me go dig up a Watch Time magazine review of the 116520...

...66 hours with chrono on... the link is here: http://www.watchtime.com/archive/wt_...001_05_042.pdf
