Having last worn a mechanical watch at school, many years ago, I recall its accuracy being around 30 seconds or so per day. It was a "Seiko 5", so a reasonable quality automatic.
I was expecting a lot better from the Cosmograph Daytona, particularly with Rolex's claims of better than COSC...
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...
