Copy "ww2.tagheuer.com/_documents/manuals/EI2246_en.pdf"" into your search engine and it will take you to a generic instruction manual for TAG watches.

This manual includes instructions for operation of your watch.

Have you a copy of the manual?

If you have, then you will see that it can be turned off (last page), is this likely to be the case?

If you need a copy, go to their web site "tagheuer.com", select "watches", then "tag heuer formula 1", then "man", followed by "Tag Heuer F1 chronometer" and finally you will see on the right a menu, select "user manual".

This seems to be a generic manual that cover both the chronometer and alarm version of the watch.

If these are not the correct instructions for your watch, opposite the "user manual" menu is a search box, put your watch model in this and there should be a user manual with it.

If not look at a similar watch for a generic manual.

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.

for manuals try this
http://world.casio.com/wat/download/en/manual/

http://www.casio.com/support

then click on watches, then manuals, and you get the model number off the back, not the front, the manuals are posted there free

Go to www.tagheuer.com
If you can't find exatly your model, don't be upset and check the closely matching models ( I mean with same features as: pushbutton count, subdials, count of hands and so on). TAG is still using the same movements as before and what you see is just different look. That means you CAN find user manual for your watch.

Good Luck
