20 Most Recent Tag Heuer WK1120.BB0314 Wristwatch Questions & Answers

Try manually winding it (assuming it's not a quartz watch). If a mechanical watch is not worn daily it will run down and need to be manually wound to get going. Turn the crown clockwise about 40 turns.

Has it broken, or just been bent out of shape??? If it is just bent you could possibly take it to a TAG repairer or a watch maker to get it adjusted

sounds like the crown stem may have snapped. Same happened to me and it had to be replaced at a cost of NZD$300. Have you bumped the watch or maybe tighted the stem too tight?

does it have screw down crown if so you need to unscrew it anti clockwise once you do this you can set time etc if it does have screw down crown remember to scew it back its spring loaded so you need a little pressure if you dont it wont be water resistant..

This is most likely a metal band and the part you are talking about is the head piece. I do not know of any outlets that sale the head piece by itself. You will most likely have to buy a replacement band either from the watch manufacturer or an after market watch band supplier like Speidel.

thats is normal you can get them changed usually on market stalls. for a few quid. watch them they might swap it for a fake. only kidding.

Explanation is simple: your watch has jammed geartrain or some dirt particles stuck into geartrain. This is why the seconds hand was moving backwards and forwards.
Nothing to do with EOL (End Of Life) feature wich is built into watch microelectronics and signals that this is the time to replace battery by advancing seconds hand two or four seconds at once.
To open the watch you need a proper watch caseback opening tool, but I can't see any reason for doing that as you will not be able to fix the geartrain problem without proper knowledge and skills.
If the warranty of the watch is expired, you don't need a TAG specialist as you will be charged for job anyway. So, find your nearest watchmaker shop and ask for repair.
