My tag heuer carrera stop watch doesnt reset properly, when u reset the stopwatch it goes one minute behind and doesnt reset to zero. how do i fix this. it never resets to zero and the red hands on the sub dials are always one or two places off. Should i take it back to Tag heuer for a service???

see link below. If the instructions available from the link below are of no use consult the supplier, they should be happy to provide support for an expensive item such as this.

Good luck, as the guy on the video says it is complicated!

Pull out the middle dialer once then try if that's doesn't work pull it again one will be the chronograph the other will be the stopwatch and if you turn the middle dialer it will change your clock

If your watch is "automatic" then would I be right in thinking you took it off for a few days and it stopped?

If this is the case (since most of the Carrera range are automatic, then the spring will have run down and needs re-winding.

You were correct in thinking that shaking it will re- start it but to keep it going you need to shake it gently from side to side for some time. (One supplier quoted 500 times!) be patient and keep wearing it.

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.

Are you aware that these are automatic watches and need to be moved to keep the watch going, kinetic energy winds up the movement which allows it to keep going, if it is left off your wrist and in a drawer or sat stationary it will stop. Shake it violently (without dropping it) and it will restart.

Unscrew the crown and pull out halfway. Use the stopwatch buttons to advance the hand to where you want it. Then push the crown back in and screw it down. You may need to pull the crown out all the way--I cannot recall which setting controls the minute hand and which the hour hand on the stopwatch function. This has to be done every time the battery is changed.

Pull crown out to position 2 [in between unscrewed (1) and pulled all the way out (3)].  Tap Button B (bottom) to reset by step back to zero.
Incidentally, Button A works Hours register in same manner for position 2.  You can similarly reset second and 1/10th with Buttons A and B, respectively, while in position 3.  Cheers!
