Help setting the time

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

I have it in PDF file
if you still need it let me know

If you go to http://www.tagheuer.com/the-collection/tag-heuer-formula-1/men/quartz-chronograph/index.lbl?w=CAH1110.BA0850 , you will see a menu on the right of the screen.

Clcik on "user manual" to download the manual for your watch.

There are no instructions about setting the date apart from saying the date changes at midnight but you can advance the date by winding it past midnight. If you want to advance it more than one day, wind it back and then forward past midnight again. Repeat as many times as required until you reach the date you need.

How far back you need to wind the watch you will have to find by eaperimenting and observing when the date changes. You might hear a soft "click" when winding it backward, you can the wind it forward again.

You change the date the same way you change the time. The only difference being pull the crown out 1/2 way to the first click instead of all the way out.

Some watches need to have the crown unscrewed.
Try turning it anticlockwise then pull out.

If this doesn't solve your problem, go to the TAG site "tagheuer.com" and find your nearest dealer.

Go to the Tagheuer web site (www.tagheuer.com/)

Select "watches"

Select "Tag Heuer Formula 1"

Select "men"

Select "Tag heuer F1 chronometer"

On the right hand side of the screen you will a menu and the user manual is the last iten on the list.

Your TAG Heuer chronograph is fitted
with a screw-in crown and safety seals
which guarantee it to be waterproof
to 200 m (660 ft).
Position 0: Crown is screwed in
(normal position).
Important: The crown must be
screwed in correctly to guarantee
the water-resistance of the watch.
Position 1: Crown unscrewed.
To change the hour (change of time
zone) or date quickly, unscrew the
crown, pull it out to position 2 (quick
corrector) and turn it in either
direction. This mode allows you to
change the hour and the date without
any loss of minutes.
The date changes each time the
hour-hand passes midnight.
To set the time, unscrew the crown,
pull it out to position 3 (setting the
time) and turn it in either direction.
After setting the date or the
time, push the crown back and
screw in to position 0.

I did it myself.Very easy use battery #394 buy at Walmart $5 made in Germany. I bought special tool to open and close the
watch on ebay
