The backlight does not work on my nike torque watch.

No, it's not normal. Use your users guide to reset the watch.

Try the Nike service center (go tohttp://www.nike.com/timing/ to find it) . If your watch is a metal strap as shown in the picture,then you should be able to get spare links from them. You are not alone in having this problem, so they should have a ready answer.

Sorry. Nike is a complicated watch. I would contact NIKE direct. THey have a great help desk on line at :

Best regards.

If you still have those nuts and did not loose them, visit your nearest watch repair shop and ask to tighten them properly. Watchmakers are using special tool, so they can tighten them very tight. If those nuts are already gone, then you have to visit your nearest Nike dealer and ask for help. Nike do not supply parts to private owners.
Rate me, plz.

Have the battery checked! First thing that stops working is the light when the battery fails! :-)

Your battery is most likely failing. The first thing that stops working is light and sound because those functions use the most energy! When your battery voltage is below 2.5 volts the light will stop working!

You must hold start button 3 seconds, then your backlight turn on by adjust button

I had the same problem. The seller told me to reset the watch by pressing down on all four buttons at once. Sure enough, the backlight function was enabled again.

Maybe you need a fresh battery?
