If the second is ticking as normally it is not the battery. If the battery is low the second hand will advance only at 5 second intervals meaning for four seconds the second does not move and on the 5th second it will advance by five seconds. This is a feature unique to Tag Heuer.

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.

The time setting screw is more accurately called the crown which is, in your case, a 'screw down crown'. This is done for water resistance. You must first unscrew the crown before you can pull it out. When you are finished setting the watch you must screw it back in. It may require that you press in on the crown and turn it at the same time to get the threads to catch. No need to overtighten it.

I think you need to replace the battery.

Go to the TAG site and locate your nearest dealer and take it in or alternatively send it to one of their service centers.

mcdevito75 here, BEST BET, Look for a small watch repair shop in your area for a replacement band, or you may want an orginal band to maintain authenticity, a band straight from Tag Heur can be ordered.

The newer straps on TAG are generally wider than the professional series and the cost of a new genuine TAG heuer clasp or bracelet may easily exceed the costof buying an entire watch of that series used.
I recommend searching for an after-market strap/ buckle usuing your case back numbers as the search criteria.

If that buttun is pushbutton, then the fixing stopwasher has come off (inside watch).
If you meen the crown (winding and setting button), then setting lever or setting lever spring is damaged or broke.
Find your nearest watchmaker as both need professional repair and parts.

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

Hard to tell without knowing what model or caliber number (usually on back). Generally, if you pull the crown (winding knob) out all the way you can set the time. Push it ONE click in, you can set the date. Check with the manufacturers website for a book of instructions you can download.
