Omega Seamaster 300m stopped working overnight

Hi!
I have never had any problem with my Omega Seamaster serviced 2 years ago, untill today.
Bought it used 3 months. Now it seems like it wont wind up automatically anymore.
I have been using it every day the last months for about 7 hours a day.
I have not an active job tho. Do someone have any clue whats the problem?
The watch is a bit older 2001 modell.

Did you have evidence that it was serviced two years ago?

No i don't got any evidence, the seller did not have the receipt.
I delivered it in yesterday to an authorized dealer. Today it was already finished.
I did not have to pay anything for the reparation. The dealer verified that it was newly serviced, and in good condition.
And the problem was described by my girlfriend: A loose screw, that had loosened and felled down in the "balance-thing". He also said that it was a regular problem, and a quick fix.

I guess i was lucky.
