If the watch is new it should be returned under warranty for attention, do not try adjusting it yourself. It needs thoroughly checking, if its running badly with poor amplitude there’s no sense in trying to regulate it.
Are you sure the watch is running in a high state of wind? I suggest you fully wind it ( approx 30 twists of the crown), note the time, allow it to run dial- up for at least 8 hrs, then check again, Be sure to check against something reliable, a quartz analogue watch is a foolproof method.
