Hello,
I just bought a Big Pilot Spitfire with Annual Calendar and 7 Day Power
Reserve. I would like to understand the power reserve better. Does it
increase through automatic movement as one wears the watch each day or doe the
reserve increase only when the watch is wound from the crown? Mine does not
seem to increase just by wearing. I have to actually wind the watch. I am
not sure if that is a problem or the normal function.
Thank you.
