needs new battery

Hi,

I fix watches as a hobby, and I had a few that corrected this by replacing the battery. If that does not work then the quartz movement probably got wet. you would have to pop the case open remove the movement and clean it gently with a q-tip. You will also be able to see if the issue is with the plastic case that can probably be faded from wear or moisture. The plastic case can be cleaned with a q-tip with alcohol. Be careful not to get any liquids, magnets or dirt near the movement. I hope this helps! Marcelo

that is a sign the battery needs changing

Time for a new watch if it wasnt the battery.

you had to replace your watch battery, but if not, it had to be checked by Timex watch expert. there's something wrong in the module of your watch.

Scratches on watches can usually be cleaned with a mild abrasive
such as Colgate toothpaste and water.
Rub a small amount of toothpaste on the scratch in a circular motion
and then apply a dab of water, continue to to rub in a circular motion
after applying the water. Let the mixture dry and rub in a circular
motion. Repeat the above steps until the scratches fade away.
This remedy worked on my watches as well as my faded
car headlight cover.
I hope it works for you.

The battery is probably dead

Fading display is sign of a weak battery. You have to replace the battery and everything will be back to normal. Rate me, plz.

It sounds like a short circuit somewhere in the watch. A visit to the authorised dealer sound necessary.
