Hello,
I have a TAG WAR201C-0 and I can not change the day(number) and day of the week... it will only change when moving the time ahead pass 12 but still the day and date are not the correct ones... any idea how to fix this? if need to take it to the watch store, any idea how much they will charge to fix this? Thanks

 

Did you try the second position of the crown, as in:
0= crown all in (screwed-in crown).
1=crown free (push crown), you can now wind your watch.
2=crown in day/date adjustable position.
3= crown in time adjustable position.
?

 

Yes, I tried... nothing, I can only adjust time, nothing else move... any idea how much they will charge for fixing this? I have an WAR201C-0 THANKS

 

That doesn't sound good and must be the keyless works that are acting up, which means work on the movement.
I can't give you an estimate for that as I don't know the labour cost in your country at your watch-store/ service centre, but it will take two hours to fix this, hope that will be of a help.
Keep us informed about the outcome!
