Problems with pointer of stopp function need help!

[Ariso]

Hello I have a big problem.

After 3-4 times using the stoppwatch function the right stopp pointer isn't on 30. He is a minute to the right on line 1.

Someone who could tell me how I can repair this? :/

Welcome to the forums

 

Does the hand move slightly as if its loose?  It could of been caused by the sharp, fast flyback when resetting if the hand tube is not firmly on its pinion.  The only way to correct this is to remove movement, then remove hand, and refit hand in the correct position.  This is assuming you have a 7750 movement in there and not a quartz?

Yes it is a 7750. How I can remove the movement? and how can i bring the hand in the correct position? Is this over a wheel in the back?

I would not advise taking apart a A7750 if you are not very experienced and I am sure steel will agree. Keep in mind half the modders do not like messing with these and the other half are just like no way big PIA.

If you have no tools or experience, take it to a local watchsmith. It will be a 20-30 minute job for a experienced watchsmith.

Without the proper tools or some previous experience then you will ruin your watch.

 

Good luck.
