B-1 brietling the problem is ,,, you need to rotate the knob to much to change the functions

Send to brietling or a competent watch repairer who is able to get spares as brietling are a bit tight with spare parts

To change the date on the Edifice Casio wristwatch pull out the knob to set time only half way - not fully otherwise you can change the time only. Then rotate the knob ANTI clockwise until you reach the desired date and push back the knob fully to return to normal

Gently pull on the "knob" on the side of the watch. You may have to get your fingernails between the watch edge and the knob. It will pull out a little bit, then a little more. One position will change the time. The other position will change the date (if it has a date function) If it has multiple knobs/buttons, it is typically the one on the right side that doesn't have smooth edges.

Who installed the battery, are they competent?

If they are take it back to them for repair in not send it to Brietling service for repair.

This is not a DIY job.

Hi jessestaton,

All you would have to do is change the time from either the digital mode or the anolog hands , you can choose one which is incorrect and try to change it.

Now to change the analog clock's settings , you would have a button which you can manually rotate and set the time, this is how you would be able to recognise that it's for the anolog time modification.

If you need to change the digital time , all you have to do is find out buttons that are present on the watch , and then try to change the time.

Note:- If you find a circled knob , remember that could only be for anolog time change as digital time is never changed using such knobs or screws , but have seperate button for that function.

In case you have any queries, feel free to get back.

Hope this helps ..:)

Sounds pretty serious!

The most likely thing to go wrong is the balance wheel has become dislodged. The most likely cause of this is being dropped onto ahard surface.

It needs to go to a Brietling dealer for repair.

You can get advice from one of their service centers which you can locate by going to their web site- http://www.breitling.com/en/index.php#/home/. On the lower left if a small menu, choose "service centers" and fill in the required details.

You can do it only after the movement is taken out. And for glass removal you need a special press. Save your nerves and your watch - visit your nearest watch maker and ask him to do that.

The manual explains it clearly From here http://www.citizenwatch.com/CUK/English/settingsresults.asp?caliber=e870

just pull the round knob once(very lightly pull it out) and keep rotating for few seconds and the date will change.
