Once you have the part number you can search ebay and if lucky you will find the clasp there.

Make sure the voltage on the new battery is correct. Just because a battery is new does not mean it is good. That is likely the problem.

You can usually find them on ebay. That's a "Kirium " model. I think it's the one with the grey face.

Go to the TAG web site ( insert "www.tagheuer.com/the-collection/" into your search engine).

Select "Carrera"

Select "men" or "women" as appropriate.

Select the model of the Carrera you have.

On the right of the screen you will see a list of options, select "user manual"

Adjust the magnification to make the text readable.

You will find them on ebay. A few of them are not authentic, especially the ones from asia so be sure to ask that question. Used ones are 300.00 - 500.00. Used ones approx. 150.00 for one in decent shape. The WK1113 has polished center row of links so make sure you get the right one.

Probably your watch has a screwdown crown and prior to attempt any settings you have to unscrew it. Some peoples fingers are stronger then others, so, try that with a pair of plyers. Cover your crown with a soft cloth and then grip with plyers(this will avoid any damage). Thread is right handed and unscrewing is done by turning the crown anticlockwise.
After setting the time don't forget to screw the crown back- it is for water resistance.
If you are unable to unscrew the crown, that means your watch is rusty and you will need watchmakers help.
PS If the watch is rusty, you can brake the crown off while trying to unscrew it. Don't panic yet, as in this case you will need a watchmaker anyway.
Don't forget to rate, please.

Hi Dude, it's one of those things your going to cuss once you know. Just unscrew the Bezel.Thats it. Steve
