Install dial onto the movement
Your sandwich dial has a top and bottom layer. Normally they should come assembled in the kit, but if they fall off, you can reassemble them by aligning the feet and hole indicated by the arrows.
The following pictures indicate the movement dial holes (green spot):

NH35 movement
NH70 & NH72 movement
Optional: How to remove the dial
To remove the dial, simply use a screw driver, and insert it in between the dial and the movement or movement holder. Inserting the screw driver next to the dial feet will give you a better control. For Seiko NH movements, you can find slots on the movement holder for this purpose.
In this part, we will install the sapphire dial. After assembling them, we will proceed to the next part, where we install the watch hands.

FINAL CHECK!
Check for proper watch functions by winding and setting time. When hands are being turned, check if they come into contact with other hands or parts.
Check for dust or dirt on crystal, hands, dial or other parts. If needed, you can remove the case to clean the inside.
Check if the case back is securely fastened. If not, water resistance capability of the watch might be compromised.
