Watch stop ticking - Swiss Army Wenger Wenger watch

Not if it is still working without the ticks

Yes, absolutely correct , all automatic watches tick and the fake Rolexes just tick a bit slower so it is more visible.

it have the battery to be reolaced.. bring it to watch service center.

browse through my tips and you will find link for all Casio watch manual downloads.

It may be that the battery is getting near the end of its life.

The tiny particles of broken glass can stop the watch working. There isn't anythining you can do about it. The only solution is to find your nearest watch repair shop and ask for help as they definetely have all the gear and knowledge to sort it out.

Rate, please.

Your band may be too loose. This is the model that moves when worn correct?

The shaking is not the best way to restart the automatic watch as it puts slight strain on watch balance wheel and hairspring (most delicate part in watch).
As watch balance wheel is positioned paralel(leveled) to watch dial, you have to spin your watch back and forth a few times quite quickly.
(Imagine you are turning steering wheel in your car- thats the right motion). Before doing that wind up your watch a few times manually.
Right after doing that observe the seconds hand and if it is ticking just a little bit or ticking back and forth and then stops- your watch has jammed gear train and this is the reason why it stops.
If you don't have seconds hand- after shaking your watch listen for ticking and again- if it stops after short run, the gear train is to blame. In this case you will need watchmakers help as special skills and tools are needed to sort this out.
Do not forget to rate, please.
