Dial: the spacing is correct for the JAPAN 6309 - 704L T text (good sign). I can't tell if the day and date window are beveled correctly. Most aftermarket dials do not have the beveled edge. The green WATER RESIST text is a common deterioration of the original orange/red text. Overall if the day/date window bevel is pronounced like in voere's watch then I think you're looking at an original dial.
EDIT - just zoomed in on the dial and there is no bevel to the window and also the lume plots are a little too poorly applied. I'll change my opinion to AM dial unless you have more photos.
Hands: Look original to me, the lume application seiko used for the hands is different form the dial for the 6309 and often times there's a different color shade as the dial plots become more yellow/orange and the hands are white/cream.
Bezel: that's an AM insert, numbers are too thick, dots too thick, little too high from the inner edge, pearl size too small.
Case: looks in super shape from the single photo but would need more. Do you have a case back shot?
