winding, does this sound right?

[venkman]

hi guys i wonder if you can advise me

on an explorer 114270, (which of course is automatic) when the watch stops running, i know of course to give it a full 40 manual winds to give it a full wind instead of just shaking it, but shouldn't it start again if you do shake it?

my question is should it start ticking again with normal movement from your arm? i assumed the watch would start ticking again if i put it on and moved around but it did not start up again even after 30 minutes of wearing it, i had to manually wind it to get it going again and it didn't even start ticking until the 15th or so turn of the crown.

is this normal for a rolex perpetual movement, to not start ticking when it's stopped and you move it around?

thanks
