Recently got a 2009 F1 Williams watch with this movement.
Twice now using a watch winder set once at 650 bi and then 550 bi, the watch has stopped in the winder.
The instructions state 10 turns of the crown to get it moving. Other reports state up to 40 for fully wound.
I also read reports that there is an inherent weakness with this movement and that overwinding can break it, I though it would have a slip clutch ?
All in all bit confused and do want to use the winder as I wear other watches.
