路To be on the safe side I never wind mine to full resistance. Obviously after you have owned it for a while you can tell when it starts to have more resistance as you wind it. If I am wearing this watch for several days I wind it in the morning and wind it at night. I Never worry about the power reserve, it's a manual wind watch and no date, so very easy to correct the time if it runs out of power. My advice is just don't be tempted to max out its power reserve by winding it until it stops.
