Damn! My rep ROO 9'subdial doesn't reset to zero :-( ! What to do?

Hi folks,

I've just seen the 9 o'clock subdial of my AP ROO secs@12 does NOT reset back to zero. It used to, but not anymore (don't know what happened...).

Do you have a solution? I tried to run the chrono and wait for the subdial hand to move, but it doesn't work...

Thank you for your help!

Hand is probably loose. You need to get it out and reattach the hand or tighten it on the pin.

And how do I get to the hands easy?
