Rolex and Chopard
Before the current cal.3255, the most precise Rolex movement in real world conditions was the one in ladies' automatic watches; better than Gents' watches!
As privately revealed by Unidentified sources 😉
The new Chopard cal.09.01-C for 30mm cases is a well tested, little tractor with central winding rotor.
Reliable winding and precision are reasons why micro-rotor or off-centre rotor are not used by Rolex, Chopard and Patek Philippe in their ladies mainstream watches.
As Thierry Stern already hinted: the Patek Philippe cal.324 is the most precise and reliable automatic movement they make....
