Just curious how the chrono affects the power reserve if at all

tkerrmd · 13 June 2016, 08:46 AM

From my experience no and I run mine all the time

Yes it does but not by a lot if you wear it regularly. If you wind it up fully and let it run without the cronograph running vs the cronograph running without wearing it in my lose a few hours on the reserve. If your wearing it you probably won't see much of a difference.

72 hour power reserve down to 48 hours. It doesn't harm the movement though due to it having a vertical clutch.

Not sure on the Daytona, but on a manual wind Speedmaster it makes almost no difference in power reserve with chrono running or still.

Yes. But why run it when not needed.

Ditto, why?

Of course it affects it..

There is no magic perpetual motion machine yet - Work (energy) requires power - more work (the chrono running) requires additional power.

It's pretty basic physics..

Not sure if this applies to a Rolex Daytona, but the following information is from Chronocentric, a longstanding and respected resource for all things chronograph:

"Is it okay to leave my chronograph function running all the time?

On most mechanical chronographs, yes it is okay. Some people prefer to do this in order to have the large second hand running. There is no evidence this causes any additional wear of any significance to the watch. It also makes little difference in the power reserve on your mechanical watch. Omega reports that their watches should lose less than 2% of their power reserve having the chronograph running continuously."

Exactly!

Running the Chrono every now and then for a day or two will let you know how well it's working.

But if you never stopped it and weren't very active, the ~72 hr. reserve will be diminished.
