Ultimately the rate of auto-winding will, as you suspect, depend how active you are. The movements in these watches self-wind somewhat less efficiently than those of, for example, Seiko, and so the advice about hand-winding seems sensible.
Need a little help regarding working of automatic watches:
Sourab Supreme is my first automatic watch, on manual winding it runs for 40-45 hour without me wearing it for any time at all. But when I put it on wrist from a dead position, it runs for about as much time as wrist time - Yesterday I wore it for 10 hours and it ran for about 11 hours. Am I doing something wrong with how I should wear it? Does it need a combination of winding and wearing? Or the less running hours are due to less frequent wrist movements in wearing time? Hope the watch by itself is fine.
