I take it you were using the ball point pen nib method, how much resistance is there when turning the bezel does it feel quite firm or loose still ,if loose it may be worth removing the bezel checking everything is clean and in place then refitting.
When I replaced mine there was a definite click when it was seated properly.
Seiko movements cannot be handwound
Note i said not all ,the 7S26 cannot be for example and that is probably one of the most common movements they use.
Back on topic you might be best buying a case with a knackered movement in for spares such as the bezel.
And regards the timekeeping you can try regulating it yourself but you will only need the tiniest of adjustments to make a difference.
