Wind the watch fully by the crown, leave it on the table and count the time until it stops.
That will show you how much power reserve there is. If it stops sooner than it's power reserve should be (in the specs), something is wrong with winding mechanism. If power reserve is about right, but your watch stops after few days of wearing it, it's that your are not active enough to wind it via rotor (or something is wrong with winding it by rotor).

All good advice from Newb!You can't overwind an automatic watch so you can give it 50 or 60 turns to ensure it's fully wound. Then do as Bnewbie says - i.e. set it down and don't touch it until it stops. If the time taken to fully wind down is within specs then the manual winding and mainspring/escapement mechanisms are working fine, so you can fully wind it again and then wear it as you normally do. Again, as Bnewbie says, if it stops after a similar (or only slightly longer) period of time, then you either aren't wearing it for long enough for it to adequately wind itself, or you aren't active enough, or there's something wrong with the automatic winding mechanism.
