A few things i noticed. If the clock hands are black, then i do not see a change in hue color. 
they will have to be some color other than black or shades of grey ex..red ,blue ........can be a comdination black and red only the red would be affected
The other thing I noticed is that when exported and I open it, the clock is black so I have to click the hue button to see the origal clock color, then it is fine
in the section that says
Sub Object_OnScriptEnter
    DesktopX.Object("3Dmetal_Clock_Face").hue = 1000
    DesktopX.Object("3Dmetal_Clock_Hours").hue = 1000
  DesktopX.Object("3Dmetal_Clock_Minutes").hue = 1000
  DesktopX.Object("3Dmetal_Clock_Seconds").hue = 1000
End Sub
Try changing the 1000 to 0
that should fix it
if you know a tutorial to create the hands or to download some .
I don't know of a tutorial but if you make them then make sure you save each one pointing at 12 so they apply correctly!
Hope this helps let me know if I can do anything!   A/V
