Watch has new battery but suddenly stopped.

why not just take to a watch/jewellery store and get battery changed

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.

are you sure you didn't just stop the chronograph?

When was the last time you had the battery changed? Average watch will get 2-3 years battery life, depending on age and condition of watch.

Any Tag Heuer dealer should be able to change your battery for you. Just go to Tag Heuer's website for a store locator. Or, just go to a search engine and type in "Authorized Tag Heuer Dealer *location*, *location*" whereas location is where you live. You will get a list of stores near you. Call them first to make sure they can do it and you're set.
Good Luck.

Unscrew the crown like you are setting the time. Make sure the time shown on the watch is not around 12 o'clock. If it is change the time to around 6 o'clock.

Then pull the crown out to the first click. Turn the crown to advance the date. When finished push the crown back in and screw it down tight.

Hope this helps,

Hi.  I just received the Tag Heuer Indy 500 with steel bracelet today for christmas from my wife.  I'm a smaller man and had to take out 3 links.  I'd never sell this watch so if you would like them...just write. [email protected]
