I got this from a buddy

Hi there,

I had the case back opened and saw this

the rotor moves both ways, clockwise and anti. Its keeping damn excellent time

There is a stamping "NN" on the movement.

Is this a 21j movement or an eta clone?

Thanks

This is an Asian DG 2813 movement with 21 jewels indeed and 21,600 BPH. Nothing to do with ETA. It's a $15 movement which performs rather good. Some complain it has a short power reserve. The rotor is supposed to move in both directions but it will only wind in one, this is normal. If runs okay now, it will probably run okay in the future...
