Tag Heuer 2000 Exclusive Qtz Chrono CN1110.BA0337

You need sharp nose pliers to unscrew the back and small screw driver to pry out the battery for direct replacement.Maybe 325 but you have to buy fresh ones from Radio Shack not drug stores.

Tag Heuer watches are constructed with scuba-diving bezels-- that is to say, it only turns COUNTERCLOCKWISE. This is so that when you are diving, you set the triangle marker to the time you went down. If you accidentally bump your watch while diving, it will move only counterclockwise, leading you to think you have LESS time left to dive, which is so much safer than thinking you have MORE time to dive, than you really do.

The date changes when the hour hand passes midnight.

If you wish to advance the date more than one day, then turn the hour hand backwards and then forwards (how far you need to go you will have to find out by experiment).

When the dateis correct, then re-set the time.

It sounds like links has been taken out previously. Check the last link ( the one that fits directly into bracelet). There must be a hole and you should be able add links.

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
