    Power Reserve Question

    I was recently timing the power reserve on a couple of my automatics and it got me wondering. Is a revolution of the rotor equivalent to a full wind of the crown? I ask bc it seems that winding the crown 10 or 20 times to jumpstart and then wearing it for a good 9 hours doesn't get it to full power reserve. I actually called the company to inquire and they said to wind it 60 to 70 times a day. Seems a bit much to me, especially for an "automatic".

    No. It takes hundreds of revolutions just to keep a watch going for one day.
