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.
