Aquaracer watch it keeps stopping

How To Set Tag Aquaracer Watch

It indicates low battery. Replace battery, No service needed.

Just replaced a women's Aquaracer battery. It's a 364. Get the SR (silver oxide type) as it will last longer.

if you are not wearing the watch it will stop the 30 minute counter

I think it depends upo which model you have but the web site does not discuss this.

Generally, if it says "automatic" then it is spring driven (does it stop if you don't wear if for a few days?).

If it keeps going, when not worn then i is a battery driven type.

You can see the range of models on their web site http://www.tagheuer.com/the-collection/aquaracer/man/leonardo-dicaprio-ltd-edition/index.lbl?w=WAJ2116.FT6022. and you may be able identify yours from their list.

When the second hand moves in short jumps rather than a smooth sweep or a second-by-second hop, it means that the battery is about to run out. Usually, with a week or two the watch will stop working altogether. You should go and have it changed as soon as possible.

Yes, there are solution for that, but you will not be able to solve it yourself as the new part is needed.
That new part is called BEZEL SPRING and it is fitted underneath the bezel.
Bezel spring has special hooks pressed into it and allows to turn the bezel one way only (anticlockwise), at the same time stopping the bezel to turn clockwise.
Another cause can be that the dirt and grime are collected between the bezel and the watch case (this is where the bezel spring is located) and is stopping functionality of the bezel spring by leting the bezel slide over the hooks. This can be fixed by cleaning the watch case in ultrasonic cleaner.
Anyway- if the bezel is rotating on its own, I suggest that the bezel spring is broke and you will need to replace it.
Do not forget to rate, please.

you bought a automatic watch, they are a quality time piece, not an acurate time piece. if you want acuacy buy a cheap quartz watch.

This is most likely the "battery change indicated" feature of your watch.  Change the battery, and see if the problem goes away.  If it does not, then it could be a problem with the stepper motor, which will require a watchmaker.  Of course all of this is dependent on the assumption that your watch has a quartz movement.  If it is an automatic, or mechanical you have bigger problems.
