Rolex Cosmograph Daytona - technical re winding

3109 Views 13 Replies 6 Participants Last post by  Jas
I have bought a Rolex Cosmograph Daytona a week ago :)

I understand the auto-wind mechanism is bi-directional, so I will use that mode on a watch winder.

My questions :)

1/ How many turns/revolutions are needed to fill its power reserve 100% from empty?

2/ How many turns/revolutions are recommended daily to keep it running, if not worn?

I do plan to wear the watch daily, but there are times when I won't e.g. when I am home over the xmas and new year period.

Daytona Cosmograph 4130 - CW (clockwise) 800-950 (turns per day) per Orbita
Thank you, I appreciate the info.

But really, this watch is not bi-directional auto winding? I thought it was.:confused:
Not the Cosmograph mov't.
I was really surprised to read that, so spent some time reading about the movement on Rolex's site.

I found this:

"Additionally, the efficiency of the self-winding mechanism has been substantially enhanced, notably with a system of new‑generation reversing wheels that allow more efficient bidirectional winding."
Like I said, the info was per Orbita. I have no idea how old it is.
I'm not a Rolex guy, I looked up the winding info only and didn't research the movement.

Maybe with a little more "Googling" you can find the info which you seek :)
